Answer:
x=-12
Step-by-step explanation:
4x−2(x+1)=3x+10
Step 1: Simplify both sides of the equation.
4x−2(x+1)=3x+10
4x+(−2)(x)+(−2)(1)=3x+10(Distribute)
4x+−2x+−2=3x+10
(4x+−2x)+(−2)=3x+10(Combine Like Terms)
2x+−2=3x+10
2x−2=3x+10
Step 2: Subtract 3x from both sides.
2x−2−3x=3x+10−3x
−x−2=10
Step 3: Add 2 to both sides.
−x−2+2=10+2
−x=12
Step 4: Divide both sides by -1.
−x/−1=12/−1
x=−12
Answer:
x=−12
Answer:
x=-12
Step-by-step explanation:
4x-2x-2=3x+10
2x-2=3x+10
2x-2+2=3x+10+2
2x=3x+12
2x-3x=3x+12-3x
-x=12
-x/-1 = 12/-1
x= -12

A phone company offers two monthly charge plans. In plan a there is no monthly fee, but the customer pays 8 cents per minute of use. In Plan B the customer pays a monthly fee of $2.40 and then an additional 7 cents per minute of use. For what amount of monthly phone use will plan a cost more than plan b? Use m for the number of minutes of phone use in a month and solve your inequality for
Answer:
[tex]m>2.40[/tex]
Step-by-step explanation:
Let m denotes the number of minutes of phone use in a month.
In plan a there is no monthly fee, but the customer pays 8 cents per minute of use.
Total cost of plan a = [tex]8m[/tex]
In Plan B the customer pays a monthly fee of $2.40 and then an additional 7 cents per minute of use.
Total cost of plan b = [tex]2.40+7m[/tex]
To find amount of monthly phone use for which plan a cost more than plan b, solve the inequality [tex]8m>2.40+7m[/tex].
[tex]8m>2.40+7m\\8m-7m>2.40\\m>2.40[/tex]
For the functions f left parenthesis x right parenthesis equals 6 minus x squared and g left parenthesis x right parenthesis equals x squared plus 4 x minus 12, find fplusg, fminusg, fg, and StartFraction f Over g EndFraction . Determine the domain for each function.
Answer:
Step-by-step explanation:
Given the functions
F(x) = 6-x²
G(x) = x²+4x-12
A) we are to find F(x)+g(x)
F(x)+G(x) = 6-x²+x²+4x-12
F(x)+G(x) = 6+0+4x-12
F(x)+G(x) = 4x+6-12
F(x)+G(x) = 4x-6
The domain of the function is the values of x for which the expression exists. The expression exists on all real interval i.e xER
F(x)-g(x) = 6-x²-(x²+4x-12)
F(x)-g(x) = 6-x²-x²-4x+12
F(x)-g(x) = 6-2x²+4x+12
F(x)-g(x) = -2x²+4x+6
The domain of the function is the values of x for which the expression exists. The expression exists on all real interval i.e xER
3) F(x)/G(x)
= 6-x²/x²+4x-12
The domain of the function is the values of x for which the expression exists. The expression exists on all real interval i.e xER

3/5 (2m-10)=2/3m+10
Answer:
m = 30
Step-by-step explanation:
3/5 (2m-10)=2/3m+10
Distribute
6/5 m - 6 = 2/3m +10
Subtract 2/3 m from each side
6/5 m - 2/3 m - 6 = 2/3m -2/3m +10
6/5 m -2/3m - 6 = 10
Add 6 to each side
6/5 m -2/3m - 6+6 = 10+6
6/5m -2/3m = 16
Get a common denominator of 15
18/15 m - 10/15 m =16
8/15 m = 16
Multiply each side by 15/8
15/8 *8/15 m = 16*15/8
m = 30
Please help ill give brainlist
Answer:
c. m∠2 = m∠5
Step-by-step explanation:
We can check 1 by 1 and find the false one.
For answer A, measures 2 and 4 are vertical angles, which means they are equal, so that's not false.
For answer b, measures 4 and 8 are corresponding angles, since X and Y are parallel, so that's also not false.
For answer c, measures 2 and 5 are supplementary to each other, and since the transversal is not perpendicular to X nor Y, they are not equal, therefore, this is false, making that the answer.
For answer d, measure 2 and 6 are corresponding angles, so that's also not false.
Therefore, the answer must be c.
Alonso went to the market with $55 to buy eggs and sugar. He knows he needs a package of 12 eggs that costs
$2.75. After getting the eggs, he wants to buy as much sugar as he can with his remaining money. The sugar he
likes comes in boxes that each cost $11.50.
Let S represent the number of boxes of sugar Alonso buys.
1) Which inequality describes this scenario?
Choose 1 answer:
2.75 + S < 55
2.75 +S > 55
2.75 + 11.50S < 55
(D
2.75 + 11.50S > 55
Answer:
2.75 + 11.50S < 55
Step-by-step explanation:
eggs + (sugar(quantity)) must be less than available money
2.75 + 11.50S < 55

Answer:
107
Step-by-step explanation:
it looks like a right angle
Answer:
The answer is 107 degrees.
Step-by-step explanation:
The sum of all the angle of a triangle must equal 180 degrees. That being said if you grab 180 and subract 44 and 29 from it you get 107 degrees. 107+44+29=180. If this did not equal 180 the answer would be wrong but since it does it is right.

explain how using fraction strips with like denominators makes it possible to add fractions with unlike denominators.
Fraction strips uses (least) common denominators, thus splitting big fraction into sum with like denominators and thus making addition possible.
Fraction strips require three major steps.
1. Firstly convert the problem with modelling as fraction strips.
2. Find the common denominator which should be least of all.
3. Now calculate the sum on new converted fractions.
For example:
[tex]\begin{aligned}\dfrac{1}{2} + \dfrac{3}{4} &= \dfrac{1}{4} + \dfrac{1}{4} + \dfrac{3}{4}\\&= \dfrac{2}{4} + \dfrac{3}{4}\\&= \dfrac{5}{4} = \: Ans.\end{aligned}[/tex]

Answer:
D
Step-by-step explanation:
It cannot be A or B because you already have both of your angles, and it cannot be C because the sides do not line up. By the process of elimination it will be D.
Answer:
D
Step-by-step explanation:
AAS = angle angle side
we already have the 2 angles so it cant be A or B. we need to find the equal corresponding side lengths. C is incorrect because side BC is not corresponding to side DF. therefore, it is D. sorry im bad at explaining but i hope this helped :)

The perimeter of a child's rectangular sandbox is 18 feet. Part A:if the length of the sandbox is one foot longer than the width, write an equation that can find the length and width of the sandbox. Part B:using your equation from part a, find the dimensions of the Childs sandbox. Show your work
Answer:
Length = 5 feet
Width = 4 feet
Step-by-step explanation:
Perimeter of the sandbox = 18 feet
Perimeter of a rectangle = 2(length + width)
the length of the sandbox is one foot longer than the width
Let
Width = x
length = x + 1
Perimeter of a rectangle = 2(length + width)
18 = 2{(x+1) + x}
18 = 2{x + 1 + x)
18 = 2(2x + 1)
18 = 4x + 2
4x = 18 - 2
4x = 16
Divide both sides by 4
x = 16/4
= 4
Width = x = 4 feet
length = x + 1
= 4 + 1
= 5 feet

1-6. Indicate whether each table or graph represents a proportional
relationship or a non-proportional relationship.
pls answer! nobody answer right and I am sick of failing this is for a mastery
Answer:
Step-by-step explanation:
Proportional relationship means,
x ∝ y
x = ky
[tex]\frac{x}{y}=k[/tex] where 'k' is the proportionality constant.
From table (1),
[tex]\frac{1}{5}=\frac{2}{9}\neq \text{Constant}[/tex]
Therefore, relationship is not proportional.
From table (2),
[tex]\frac{1}{6}=\frac{3}{18}=\text{constant}[/tex]
True.
So the relationship will be proportional.
From table (3),
[tex]\frac{\text{hours}}{\text{Miles}}= \frac{2}{110}=\frac{5}{175}=\frac{1}{55}[/tex]
Which is constant.
Therefore, relationship will be proportional.
From table (4),
[tex]\frac{\text{Hours}}{\text{Paid}}=\frac{3}{29.25}=\frac{5}{48.75}=0.103[/tex]
Which is constant for every term.
Therefore, relationship will be proportional.
