Don't be worried friend :)
-(y + 2) + 8 = 3
=> -(y + 2) = -5
=> y + 2 = 5
=> y = 3
Solve each equation for the indicated variable. u = -3a - 3 , for a
Answer:
[tex]a = \frac{u + 3}{-3}[/tex]
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 3 to both sides of the equation:
u = -3a - 3
u (+3) = -3a - 3 (+3)
u + 3 = -3a
Next, divide -3 from both sides of the equation:
(u + 3)/-3 = (-3a)/-3
a = (u + 3)/-3
[tex]a = \frac{u + 3}{-3}[/tex] is your answer.

Admission to a local aquarium is $10 for
adults and $7 for children. The aquarium
collected $6,549 from the sale of 783
tickets. Find the number of adult tickets and
children tickets that were sold.
First, let's define variables:
A = adults
C = children
Okay, now that's done, time to set up the two equations required to solve:
10a + 7c = 6549
a + c = 783
One way you can solve this is to set up the second equation to isolate a variable. For example,
a = -c + 783
Using this, we can plug it into the first equation and solve for c.
10(-c+783) + 7c = 6549
-3c = -1281
c = 427
Now, use the value of 427and plug it in either equation to solve for a.
a + 427 = 783
a = 356
356 adult tickets were sold, and 427 children tickets were sold.

Write 0.42 as a fraction in simplest form.
Answer:
21/50
Step-by-step explanation:
First, convert to a fraction. Since its hundredths place, the fraction is 42/100
Next, simplify. The GCF is 2, so you divide each number by 2, to get 21/50
Answer:
21/50
Have a nice day! :D
Step-by-step explanation:
Write a fraction for which the sum of the numerator and denominator is 44, and the value of the fraction is 5/6.
Answer: [tex]\frac{20}{24}[/tex]
Multiply each sides of the fraction (numerator/denominator) by 4.
5 x 4 = 20, 6 x 4 = 24
Make a fraction out of 20 and 24.
20/24 = [tex]\frac{20}{24}[/tex]
Make sure the fraction is correct, by adding.
20 + 24 = 44
Answer = 44
The distance of a golf ball from the hole can be represented by the right side of a parabola with vertex (-1,8). The ball reaches the hole 1 second
after it is hit, at time 0.
What is the equation of the parabola, in vertex form, that represents the ball's distance from the hole, y, at time x?
y =
(x +
Answer:
Let's suppose that the hole is at y = 0m, where x is the time variable.
we know that:
The vertex is (-1s, 8m).
(i suppose x in seconds and y in meters)
At x = 1s, the ball reaches the hole, so we also have the point:
(1s, 0m).
Remember that the vertex of a quadratic equation y = a*x^2 + b*x + c is at:
x = -b/2a,
then we have:
-1 = -b/2a.
Then we have tree equations:
8m = a*(-1s)^2 + b*-1s + c
0m = a*(1s)^2 + b*1s + c
-1s = -b/2a.
First we should isolate one variable in the third equation, and then replace it in one of the other two:
1s*2a = b.
So we can replace b in the first two equations bi 1s*2a.
8m = a*1s^2 - 1s*2a*1s + c
0m = a*1s^2 + 1s*2a*1s + c
We can simplify both equations and get:
8m = a*( 1s^2 - 2s^2) + c = -a*1s^2 + c.
0m = a*(1s^2 + 2s^2) + c = a*3s^2 + c.
Easily we can isolate c in the second equation and then replace it into the first equation:
c = -a*3s^2
The first equation becomes:
8m = -a*1s^2 - a*3s^2 = -a*4s^2
a = 8m/-4s^2 = -2m/s^2.
Now with a, we can find the values of c and b.
c = -a*3s^2 = -(-2m/s^2)*3s^2 = 6m.
b = 1s*2a = 1s*(-2m/s^2) = -2m/s.
Then the equation is:
y = (-2m/s^2)*t^2 + (-2m/s)*t + 6m

HELP !!! will mark as brainliest ✓
Answer:
x=160°, y= 62°
Hope this helps
Answer:
∠X = 160°, ∠Y = 62°
Step-by-step explanation:
∠ABD = ∠FDC = 20° [ DF║AB ]
∠X = 180° - ∠FDC
∠X = 180° - 20° = 160°
∠FCD = ∠BCA = 98°
∠Y = ∠CAB [ DF║AB]
∠BCA+∠CAB+∠ABC = 180°
98°+∠CAB+20° = 180°
∠CAB = 180° - 118° = 62° = ∠Y

Chad's baseball team is practicing hitting in the batting cages. The pitching machines pitch baseballs at a rate of 35 pitches in 5 minutes. Chad practiced hitting for 8 minutes.
How many baseballs were pitched to Chad in that time?
Answer:
56 baseball's
Step-by-step explanation:
The number of baseballs were pitched to Chad in 8 minutes is 56.
What is the unit rate?Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
Given that, the pitching machines pitch baseballs at a rate of 35 pitches in 5 minutes.
Number of pitches hit in 1 minute = 35/5
= 7
Chad practiced hitting for 8 minutes.
So, the number of baseballs were pitched = 7×8
= 56
Hence, the number of baseballs were pitched to Chad in 8 minutes is 56.
