Answer:

y = 2x + 3

Step-by-step explanation:

because the y intercept is 3 based on the graph then i found two points (-4,1) and (-2,2) then i used solved. -4+2=-2 , 1-2 =-1  which means that you get -2/-1 which equals 2

Answer:

50 + 20x = y

(you should get a second opinion)

Answer:

y=20x+50

Step-by-step explanation:

In slope-intercept form y=mx+b,

y is determined after the x value is plugged in

m is the slope (in this case it's 20)

x is the value you plugin

and b is the y-intercept; this value does not change

put it all together and you get y=20x+50

Hope this helps!

Answer:

B. 77

Step-by-step explanation:

because (72 + 97 + 82 + 77) ÷ 4 = 82

Pls Brailniest! ;) It would mean a lot.

Answer:

77

Step-by-step explanation:

If you add all the numbers you would get 251 and if you divide that by 3 you get 83.67. So what I did to get a mean of 82 was add those 3 numbers then the individual answer choice. so 72+97+82+77=328. 328/4 is equal to 82

Answer:

-17.3

Step-by-step explanation:

Evaluate 5 x + x/2 - 29.4 where x = 11/5:

5 x + x/2 - 29.4 = 5×11/5 - 29.4 + 1/2×11/5

Hint: | Express 5×11/5 as a single fraction.

5×11/5 = (5×11)/5:

(5×11)/5 - 29.4 + (11/5)/2

Hint: | Express (11/5)/2 as a single fraction.

(11/5)/2 = 11/(2×5):

(5×11)/5 - 29.4 + 11/(2×5)

Hint: | Cancel common terms in the numerator and denominator of (5×11)/5.

(5×11)/5 = 5/5×11 = 11:

11 - 29.4 + 11/(2×5)

Hint: | Multiply 2 and 5 together.

2×5 = 10:

11 - 29.4 + 11/10

Hint: | Approximate 11/10.

11/10≈1.1:

11 - 29.4 + 1.1

Hint: | Evaluate 11 + 1.1 using long addition.

| 1 | 1. | 0

+ | | 1. | 1

| 1 | 2. | 1:

12.1 - 29.4

Hint: | Factor out a negative sign in 12.1 - 29.4 in order to subtract.

12.1 - 29.4 = -(29.4 - 12.1):

-(29.4 - 12.1)

Hint: | Subtract 12.1` from 29.4`.

Answer:

950 feet

Step-by-step explanation:

the area of a triangle is a=(bh) 1/2

plug in the values for a triangle into that equation, then do it to the other triangle.

add the solutions to get 150 feet

then find the area of the rectangle: 20 x 40= 800

add 800 and 150 to get the total area: 950 feet

Step-by-step explanation:

Solution for 0.5 is what percent of 7.5:

0.5:7.5*100 =

(0.5*100):7.5 =

50:7.5 = 6.6666666666667

Now we have: 0.5 is what percent of 7.5 = 6.6666666666667

Question: 0.5 is what percent of 7.5?

Percentage solution with steps:

Step 1: We make the assumption that 7.5 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=7.5$.

Step 4: In the same vein, $x\%=0.5$.

Step 5: This gives us a pair of simple equations:

$100\%=7.5(1)$.

$x\%=0.5(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{7.5}{0.5}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{0.5}{7.5}$

$\Rightarrow x=6.6666666666667\%$

Therefore, $0.5$ is $6.6666666666667\%$ of $7.5$.
