8=16+(y-1)
how do i solve this?
Answer:
y=-7 :)
Step-by-step explanation:
remove the parentheses
8=16+y-1
subtract the numbers
8=15+y
move variable to the left-hand side and change it's sign
-y=15-8
subtract the numbers
-y=7
change the sides on both sides of the equation
y=-7
hope it help <3
Answer:
y=2
Step-by-step explanation:
8= 16y + 16
16-8= 16y
8= 16y
y= 2
A 3-gallon tub of ice cream yields about 90 scoops of ice cream. There are roughly 3785 cubic centimeters in 1 gallon. Determine the radius of each scoop, to the nearest tenth.
Answer:
The radius of the scoop is r = 3.1 cm
Step-by-step explanation:
Since 3 gallons yields 90 scoops, and 1 gallon = 3785 cm³.
3 gallons = 3 × 3785 cm³ = 11355 cm³
So we have 11355 cm³ in 3 gallons which is also the volume of 90 scoops.
Since 90 scoops = 11355 cm³, then
1 scoop = 11355 cm³/90 = 126.2 cm³
Now, if each scoop is a sphere, the volume is given by V = 4πr³/3 where r is the radius of the scoop. Since we need to find the radius of the scoop, r, making r subject of the formula, we have
r = ∛(3V/4π)
Substituting V = 126.2 cm³, we have
r = ∛(3× 126.2 cm³/4π)
= ∛(378.6 cm³/12.57)
= ∛30.13 cm³
= 3.1 cm
So, the radius of the scoop is r = 3.1 cm

the volleyball boosters sell bags of popcorn during the varsity matches to raise money for new uniforms. each bag of popcorn costs $3
Does anyone know how to solve this? I really need help please.
Answer:
See Below
Step-by-step explanation:
angle BAK = 128
Find KAS
180 - 128 = 52
KAS = 52
find BKA and ABK
360 -128 = 232
232/2 = 116
BKA =116
ABK = 116
find AKS
180 - 116 = 64
AKS =64
Now you have KAS and AKS
add together and subtract sum from 360 to find BSK
52 + 64 = 116
360 - 116 =244
Let me know if incorrect, plz.

Given g(x) = 3x+3, find g(6)
Answer:
g(6)=21
Step-by-step explanation:
Given g(x)= 3x+3, Find g(6)
1. Replace g(x) with g(6), and x with 6. The equation will now look like this: g(6)=3(6)+3
2. Multiply 3 and 6, to equal 18. The equation will now look like this: g(6)=18+3
3. Add 18 and 3 to equal 21. The Answer is g(6)=21

What is the slope of a line that is perpendicular to the graphed line?
Answer:
2
Step-by-step explanation:
To find the slope of the graphed line, you take two points. I have chosen (0, 4) and (8, 0)
The formula of a slope is (y value of second point [tex]-y[/tex] value of first point) divided by (x value of second point [tex]-x[/tex] value of first point):
[tex]\frac{0-4}{8-0} =-\frac{1}{2}[/tex]
