Answer:
6. b. 50
7. d. 12
Step-by-step explanation:
6. 80% is equal to 0.8.
0.8x =40.
Divide 0.8 by 40 to get x.
x=50.
7. If he needs 3 eggs for 30 cookies, we divide 120 by 30 to get 4.
We multiply 4*3 to find the total amount of eggs needed.
4*3= 12
Answer:
||w|| = 6
Step-by-step explanation:
||w|| = modulus or magnitude of vector w
Since formula to get the modulus of any vector =
Vector w = <-6, 0>
x-component of vector w = (-6)
y-component of vector w = 0
Therefore, ||w|| =
= 6
<span>y -3x = 2
y = 3x + 2 so slope = 3
parallel lines, slope is the same so slope = 3
</span><span>passes through (6,1)
</span>y = mx + b
b = y - mx
b = 1 - (3)(6)
b = 1 - 18
b = -17
equation
y = 3x - 17

3/2 is the same 15/10 so the answer. there are 3 boys to every 2 girls 9/6 the answer. 9 boys and 6 girls
The answer would be the first one, combining 8 and -2
This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)
If you combine these you will get 6x^2 [8+(-2)=6]
