Can you simplify 7+4(x+5)

Answers

pemdas
first distribute
distributive property
a(b+c)=(ab)+(ac)
ac=a times c

so 4(x+5)=(4*x)+(4*5)=4x+20
7+4x+20=4x+27

7+4(x+5), expand the brackets by multiplying 4 & x 4 & 5
7+4x+20, add 7 & 20 together
27+4x, Here is the result

Sandra runs a water slide at the water park and needs to count the people who go down the slide. At the beginning of her shift, 178 people had gone down the slide. The table shows the total number of water sliders for several times during Sandra's shift.Hours into Sandra's shift

What is the equation in slope-intercept form that represents the total number of water sliders over time?

Choose the correct expressions from the drop-down menus to create the equation in slope-intercept form.

Answers

The table of total number of water sliders is an illustration of a linear function.

The equation in slope intercept form is: $\mathbf{y = 46x + 178}$

From the table, we have the following points.

$\mathbf{(x_1,y_1) = (0,178)}$

$\mathbf{(x_2,y_2) = (1,224)}$

Calculate the slope (m)

$\mathbf{m = (y_2 - y_1)/(x_2 - x_1)}$

So, we have:

$\mathbf{m = (224 - 178)/(1 - 0)}$

$\mathbf{m = (46)/(1 )}$

$\mathbf{m = 46}$

The linear equation is then calculated as:

$\mathbf{y = m(x - x_1) + y_1}$

So, we have:

$\mathbf{y = 46(x - 0) + 178}$

$\mathbf{y = 46x + 178}$

Hence, the equation in slope intercept form is: $\mathbf{y = 46x + 178}$

What is the best estimate for the sum of 3/8 and 1/12

Answers

I would round the 8 in 3/8 to ten, along with roundin the 12 in 1/12 to 10 as well. Now you would have 3/10 + 1/10, = 4/10 or 2/5 simplified. Hope this helps, (as this would be my estimate!)

a pedestal in a craft store is in the shape of a triangular prism. The bases are right triangles with side lengths of 12 centimeters, 16 centimeters, and 20 centimeters. The store owner wraps a piece of rectangular cloth around the pedestal, but does not cover the identical bases of the pedestal with cloth. The area of the cloth is 192 square centimeters. What is the distance around the base of the pedestal? how do you know? What is the height of the pedestal? how did you find your answer?

Answers

You found your area wrong as soon as you gt 192 you multiply by 0.50 getting 96 then you divide by 20 to get 4.8 centimeters
