1. Y=2

2.A=1.3

5.p=28/3

Answer:

1. 5 + y = 7

⇒ y = 7 - 5

⇒y = 5

2. 3.8 = a + 2.5

⇒ a = 2.5 - 3.8

⇒ a = -1.3

3. 5 + p = 9 1/3 

⇒ p = 9 1/3 - 5

⇒ p = 28/3 - 5

⇒ p = 28/3 - 15/3

⇒ p = 13/3

⇒ p = 4 1/3

For function of g,g(0)=1 and g(1)=5 assuming g is a linear function what is g(3)

lawyer [7]

Answer:

$g(3) = 13$

Step-by-step explanation:

Given

$g(0) = 1$

$g(1) = 5$

Required

Find g(3)

Since g(x) is a linear function, then:

$g(x) = mx + c$

For: $g(0) = 1$

$g(x) = mx + c$

$g(0) = m*0 + c$

$1 = 0 + c$

$1 = c$

$c = 1$

For: $g(1) = 5$

$g(x) = mx + c$

$g(1) = m * 1 + c$

$5 = m * 1 + c$

$5 = m + c$

Substitute $c = 1$

$5 = m + 1$

$m = 5 - 1$

$m =4$

So, the function is:

$g(x) = mx + c$

$g(x) = 4x + 1$

Calculate g(3)

$g(3) = 4*3 + 1$

$g(3) = 12 + 1$

$g(3) = 13$

What is the measure of angle A

stellarik [79]

Answer:

The angle of A is 80°

Step-by-step explanation:

Given that angle A lies on a straight line which is 180°. So in order to find A, you have to substract 100° from 180° :

∠A + 100° = 180°

∠A = 180° - 100°

∠A = 80°

What is 21 1/4% expressed as a fraction?

Neporo4naja [7]

Answer:

$\frac{17}{80}$

Step-by-step explanation:

we have

$21\frac{1}{4}\%$

Convert mixed number to an improper fraction

$21\frac{1}{4}=21+\frac{1}{4}=\frac{21*4+1}{4}=\frac{85}{4}$

$21\frac{1}{4}\%=\frac{85}{4}\%$

Convert percent number as a fraction

$\frac{85}{4}\%=\frac{85}{4}:100=\frac{85}{4*100}=\frac{85}{400}$

Simplify

Divide by 5 both numerator and denominator

$\frac{17}{80}$
