4/1 = 2/x...4 miles to 1 hr = 2 miles to x hrs
cross multiply because this is a proportion
(4)(x) = (1)(2)
4x = 2
x = 2/4 reduces to 1/2...so she can walk 2 miles in 1/2 hr (or 30 minutes)

3.y=-2x+5

4.y=4x

5.y=4x-4

6.y=-2x-5

Step-by-step explanation:

(i)

y=mx+c

10=(m)3+1

10=3m+1

Answer: <u>96</u> sq ft.

Step-by-step explanation:

      First, we will find the area of the rectangular sides. Since the triangle is an equilateral triangle, all the rectangles will be the same size.

             A = L * W

             A = (10 ft) * (3 ft)

             A = 30 ft²

             30 ft² * 3 = 90 ft²

      Next, we will find the area of the two triangles.

             A = \frac{b*h}{2}

             A = \frac{3*2}{2}=\frac{6}{2} =3

             3 ft + 3 ft = 6 ft²

      Lastly, we will add them together for the total surface area.

90 ft² + 6 ft² = 96 ft²

I need helps with this question ASAP

Answer:

1. At Kohls Mrs. House would pay $45.00 because %25 = $15 so I just subtracted %.60.00-$15.00.

2.((Number × Percent/100)) + Number

((38 × 15/100)) + 38

5.7 + 38

= 43.7

3. I say that Mrs. House should go-to target. And just by $1.30.

At Kohls, the speaker would be at $45.00.

At target, the speaker would be at $43.70.

$45.00 - $43.70 = $1.30

Find the value of x. *<br> I think I’m a little off
DiKsa [7]

Answer:

x = 44

Step-by-step explanation:

3x - 5 is complementary to y° so their sum is 180°

The angle with measure 127° is also complementary with y°

127 + y = 180

y = 53°

53 + 3x - 5 = 180

3x + 48 = 180

3x = 132

x = 44
