Evaluate the expression for the given value of the variable
1. 8q + 6; q = 2
Plug in 2 for q in the given expression
8(2) + 6= 22
2. 9 + 4g; g = -3
9 + 4(-3) = 9 - 12 = -3
3. 7x - 7 ; x = 4
7(4) - 7 = 28 -7 = 21
4. 10 - 3.2n; n = 2
10 - 3.2(2) = 10 - 6.4 = 3.6
5. 12p + 4; p = 1.5
12(1.5) + 4= 18 + 4 = 22
6. 5w + 10 = 40
Subtract both sides by 10
5w = 30, now divide both sides by 5
w = 6
7. 4y - 12 = 60
Add both sides by 12
4y = 72
Now divide both sides by 4
y = 18
8. 10k + 5 = 65
Subtract both sides by 5
10k = 60, now divide both sides by 10
k = 6
9. 2b - 15 = 33
Add both sides by 15
2b = 48
Now divide both sides by 2
b = 24
10. 3d + 18 = 21
Subtract both sides by 18
3d = 3, now divide both sides by 3
d= 1
The value of the expression is 38.5
Answer:
i need the table
Step-by-step explanation:
But usually it has something to do with an exponent
So the fraction would be 23/35 are boys. If you do the division (23 ÷ 35) the answer is around 0.657.
That converted into a percentage (×100) is 65.7%
