Write the word sentence as an equation. Then solve. The sum of a number y and −3 is −8.
Answer:
y = -5
Step-by-step explanation:
Step 1: Translate
"Sum" is addition
"a number y" is y
"-3" is -3
"is -8" means equal to -8
Step 2: Set up equation
y + -3 = -8
Step 3: Solve for y
Simplify: y - 3 = -8Add 3 to both sides: y = -5y=7x+ 2/5 as standard form

what is wrong with the equation?
Answer:
x = 3
Step-by-step explanation:
We don't know what equation you think is wrong.
__
The solution to the problem is ...
x/2 +x/6 = 2
x(1/2 +1/6) = 2 . . . . working using the given fractions
x(3/6 +1/6) = 2
x(4/6) = 2
x(2/3) = 2
x = (3/2)(2)
x = 3

We can also work this by eliminating fractions first.
x/2 +x/6 = 2
3x +x = 12 . . . . multiply the equation by 6

i know she graphed it correctly but i don't know the steps she took to graph it
She graphed it correctly.
The inequality [tex]3y \le 2x[/tex] is the same as [tex]y \le \frac{2}{3}x[/tex] after dividing both sides by 3 to isolate y.
From here you graph [tex]y = \frac{2}{3}x[/tex] which is a straight line through (0,0) and (3,2). This line is made solid because of the "or equal to" as part of the inequality sign above.
We shade below the solid boundary due to the "less than" portion of the inequality sign.

A line passes through the points (-6, 4) and (-2, 2). Which is the equation of the line?
O y--3x+1
O y-5x+7
O y = -2x - 8
O y = 2x + 16
Answer:
[tex]\displaystyle y=-\frac{1}{2}x+1[/tex]
Step-by-step explanation:
The equation of any line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Two points are given: (-6,4) and (-2,2). Calculating the slope:
[tex]\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}[/tex]
The equation of the line is, so far:
[tex]\displaystyle y=-\frac{1}{2}x+b[/tex]
To calculate the value of b, we use any of the given points, for example (-6,4):
[tex]\displaystyle 4=-\frac{1}{2}(-6)+b[/tex]
[tex]\displaystyle 4=3+b[/tex]
Solving:
b = 1
The equation of the line is:
[tex]\boxed{\displaystyle y=-\frac{1}{2}x+1}[/tex]
We can see none of the choices is correct.

18/42 + 7/42 = 25/42
Hope this helps :)
Have a nice day :)
Can you give me brainliest plz :)
Answer:
25/42
Step-by-step explanation:
You can get to 25/42 by finding the least common denominator, or in layman's terms, by seeing what the lowest number the two denominators can both EQUALLY go in to. in this case it's 42, as both 6 and 7 can go into 42 equally, and 42 is the lowest number that they both can go into. So after you find the least common denominator, you make that the denominator of both fractions, and multiply the two numerators by however many times you had to multiply the denominators by. for example, to get 7 to 42, you need to multiply it by 6, so you would then multiply the numerator, in this case it's 3, 6 times, netting you 18. you do the same thing with the other fraction, since the numerators 1, you multiply it by 7, since you had to multiply 6 by 7 to get 42. this leaves you with 18/42 + 7/42, which you can now normally add together to get 25/42, and since it can't be reduced, it stays this way. Hope this helps :)

A video game console uses 154 watt-hours of energy each hour. The console was used 276 hours last year. How many watt-hours of energy did the console use?
Answer:
The console was used 42,504 watt-hours of energy last year
Step-by-step explanation:
video game console uses 154 watt-hours of energy each hour
The console was used 276 hours last year.
How many watt-hours of energy did the console use?
Watt hours of energy used = 154 × 276
= 42,504 watt-hours of energy
The console was used 42,504 watt-hours of energy last year

10x − 6 = 24
Answer:
3
Step-by-step explanation:
10x-6=24
10x = 24+6 (You switch sides because you can add 24 and 6. You cannot add 10x to 24 or 6)
10x= 30
x= 30/10
x= 3
The answer is 3.
Answer:
x=3
Step-by-step explanation:
10x-6=24
Subtract 6 from 6 and then add 6 to 24
10x=30
30÷10=3
Divide 30 by 10

Step-by-step explanation:
Use PEMDAS

D = Division*
A = Addition**
S = Subtraction**
*either can come first, it just depends which comes first in the equation.
**either can come first, it just depends which comes first in the equation.
Step 1 : Write equation 4( 9 × 2 ) ÷ ( 4 -1 ) - 4
Step 2: Solve in parenthesis 4(18) ÷ (3) - 4
Step 3: Solve multiplication 72 ÷ 3 - 4
Step 4: Solve division 24 - 4
Step 5 : Solve subtraction 20
The simplified answers is -22.
What is order of operation?The order of Operations is the rule in math that states we evaluate the parentheses/brackets first, the exponents/the orders second, division or multiplication third (from left to right, whichever comes first), and the addition or subtraction at the last (from left to right, whichever comes first). In math, there might be several operations to be done while evaluating an expression, and simplification at the end yields different results. However, we can only have one correct answer for any sort of expression. To identify the correct answer we simplify any given mathematical expression using a certain set of rules. These rules revolve around all the basic operators used in maths. Operators such as addition (+), subtraction (-), division (÷), and multiplication (×).
The order of operation can be termed as BODMAS.

4 + (9∙2) ÷ (4 - 1) - 4

Imani is making costumes for a play. She spent $146.58 on 21 yards of fabric. Write and solve an equation to find how much Imani paid for each yard of fabric.
Multiple choice question.
A)
21p=146.58; $6.98 per yard
B)
146.58p=21; $0.14 per yard
C)
146.58(21)=p; $3078.18 per yard
D)
21p=146.58; $3078.18 per yard
Answer:
A
Step-by-step explanation:
21 yards and Total cost of $146.58
p = 1 yard
Equation: 21p = 146.58
p = 146.58/21
p = 6.98
21p=146.58 will describe the equation and the amount paid for each yard is $6.98 so option (A) will be correct.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Amount of fabric = 21 yards
Since cost per yard of fabric is given by p
So,
The total cost of fabric = Amount of fabric × cost per yard
146.58 = 21p
21p=146.58
Now,
p = 146.58/21 = 6.98.
Hence "21p=146.58 will describe the equation and the amount paid for each yard is $6.98".

If a stone tower is 15 meters tall and casts a shadow 8 meters long, then how long of a
shadow will be cast by a nearby radio tower that is 60 meters tall?
Answer:
32 meters long (please double-check! sometimes ppl make mistakes)
Step-by-step explanation:
the ratio of height to shadow length is 15:8, as established in the first sentence. if both sides of the ratio are multiplied by 4 then the ratio becomes 60:32.
more in depth:
if you think of it as fractions (which ratios can be written as) multiplying both the numerator and denominator by four is the equivalent of multiplying by 4/4 aka 1 so the value still stays the same (one times something is the same thing). since the ratio of height to shadow length is constant we needed to solve for the ratio in which the height is 60, so multiply each side by 4 (aka 60 divided by 15) to find the new ratio, 15(4):8(4) or 60:32. the ratio 60:32 describes height to shadow, so while the height is 60 (said in the problem) then the shadow length is 32. adding units, the answer would be 32 meters.
