This is the overall final answer in fraction and decimal form.
The number of boys wear glasses are 156 boys.
In this question,
Total number of pupils in the school = 910
Ratio of boys = 3/7
Then, number of boys = 910 × 3/7
⇒ 130 × 3
⇒ 390
Ratio of boys wear glasses = 2/5
Then, number of boys wear glasses = 390 × 2/5
⇒ 78 × 2
⇒ 156
Hence we can conclude that the number of boys wear glasses are 156 boys.

We already know the y intercept as it is the same value as the constant which is -2
To find the x intersept let’s set the y value to zero
0=4x-2
0+2=4x
2=4x
2/4=x
1/2=x
Therefor the y intersept is -2 and the x intersept is 0.5
Answer:
180
Step-by-step explanation:
.4 liters = 400 milliliters
22 * 10 = 220
400-220 = 180
Answer: m∠5 = m∠7 = 67°
because a//b => m∠4 + m∠5 = 180°
⇔ 113° + m∠5 = 180°
⇔ m∠5 = 180 - 113 = 67°
because ∠5 and ∠7 are 2 opposing angles
=> m∠5 = m∠7 = 67°
