Hey there!
3(q + 34)= 2
First distribute:
3(q) + 3(34)
3(q) = 3q
3(34) = 102
New equation: 3q + 102 = 2
Subtract by 102 on each of your sides:
3q + 102 - 102 = 2 - 102
Cancel out: 102 - 102 because it gives us 0
Keep: 2 - 102 because it helps us solve for our q
2 - 102 = - 100
New equation: 3q = -100
Divide both sides by 3
3q/3 = -100/3
Cancel out: -3q/3 because it gives us 1
Keep: -100/3 because it gives us the answer for q
Answer: q = -100/3 ✅
Good luck on your assignment and enjoy your day!

Answer:
x=1
Step-by-step explanation:
Y=3
to solve this you just substitute 4 in for x into the equation and solve for y. since negative 3 plus 7 is 4, y=4
Answer:
x= 4
y= -5
Step-by-step explanation:
-2x+6y=-38 equation 1
3x-4y=32 equation 2
using equation 1 we have:
-2x+6y=-38
6y +38 = 2x
3y + 19 = x equation 3
using equation 3 in equation 2 we have:
3(3y + 19) - 4y = 32
9y + 57 -4y =32
5y = 32 -57
5y = -25
y= -25/5
y = -5
so we have:
3y + 19 = x
3(-5) +19 = x
x= 4
Answer:
r = 2.55
Step-by-step explanation:
The formula for finding the radius of a circle using the area is r = √A/π
with the r being the radius. the A being the area, and the π being pi (we'll use 3.14).
So the equation should look like this:
r = √(20.4/3.14)
Find the quotient of 20.4/3.14 and round to the nearest tenth
r = √6.5
Find the square root and round to the nearest hundredth
r = 2.55
