Answer: angle y is 50°
Step-by-step explanation:
t + 2t - 30 = 90
3t -30 = 90
3t = 90+30
t = 120/3 = 40 = angle X
Angle y = 2t-30
y = 2*40-30
=80-30 = 50
Answer:
x-axis from -20 to 5; y-axis from -80 to 80
Step-by-step explanation:
The attached graph shows my choice for a viewing window. The closest approximation among your answer choices is ...
x: -20 to 5
y: -80 to 80 . . . . . choice A
Multiply -2 with x equaling -2x
Multiply -2 with +6 equaling -12
Y - 5 = -2x - 12
Add 12 on both sides
Y - 5 + 12 = -2x - 12 + 12
Y + 7 = -2x
Divide by -2 on both sides
Y + 7 / -2 = -2x/-2
Y + 7
------- = x
- 2
Short answer: 375 grams
Remark
You only need to set up a direct proportion
Givens
flour for 12 cakes = 150 grams
Number of cakes initially = 12
Amount of flouer for 30 cakes = x
Number of cakes = 30
Proportion
amount flour for 12 cakes / 12 cakes = x / 30
Sub and solve
150 grams / 12 cakes = x / 30 cakes Cross multiply
150 * 30 = 12 *x Multiply the left side.
4500 = 12 x Divide both sides by 12
4500/12 = x
375 grams for 30 cakes. <<<<< Answer
