what is the solution to the system of equations? please help im struggling really bad ):

Answers

Answer:

[tex] - 11 \frac{1}{2} [/tex]

Step-by-step explanation:

8x + 5y = 7

4x - 5y = 11

If you all it all up we have

8x + 4x +5y - 5y = 18

12x=18

x=18/12=1.5=3/2 = 1 whole number 1 over 2(1 1/2)

subtituting the value of x into equation 1(8x + 5y = 7)

8(1.5) + 5y = 7

5y=7-12

5y = -5

y=-5/5

y= -1

A 1,300 kg car moving at 20 m/s and a 900 kg car moving at 15 m/a in precisely opposite directions crash head on. If we consider this event to be a perfectly inelastic collision, what is the speed of the cars after the impact?

Answers

Answer:

17.96m/s

Step-by-step explanation:

Based on law of conservation of momentum;

m1u1 +m2u2 =(m1+m2)v

v is the velocities of the car after impact

Substitute the given values

1300(20)+900(15) = (1300+900)v

26000 + 13500 = 2200v

39500 = 2200v

v = 39500/2200

v = 17.96m/s

Hence the speed of the cars after impact is 17.96m/s

The storage box for a flag is in the shape of a triangular prism. What is the surface area of the box?

Answers

*see attachment for the diagram of the triangular prism box

Answer:

528.8 in.²

Step-by-step explanation:

Surface area of triangular prism = 2(BA) + P*H

Area of triangular base (BA) = ½*b*h

b = 24.5 in.

h = 12 in.

BA = ½*24.5*12 = 147 in.²

Perimeter of triangular base = 24.5 + 17.1 + 17.1 = 58.7 in.

Height of prism = 4 in.

Plug in the values into the surface area formula:

Surface area of prism = 2(147) + 58.7*4

= 294 + 234.8

= 528.8 in.²

The ratio of cakes to cookies in the bakery was 3:5. If there were 90 cakes, how many cookies were in the bakery?
plz help

Answers

Answer:

150 cookies

Step-by-step explanation:

Using the ratio as an equation we can divide 90 by 3 to find the common multiple used to simplify this equation into a more usable ratio.

3 : 5 90 : 5x (x is the common multiple)

90 / 3 = 30, so x is 30

Then we multiply both sides of the original ratio by the common multiple to get our answer.

3 : 5 is equal to 90 : 150

Marley walked around 2 rectangular parks. One measures 54 feet by 38 feet and the other measures 32 feet by 22 feet. How far did she walk?

Answers

Answer:

Step-by-step explanation:

Perimeter of Park 1 = 2*(54+38)

= 2 * 92

=184 feet

Perimeter of park 2 = 2*(32+ 22)

= 2 * 54

= 108 feet

Total distance = Perimeter of park 1 + perimeter of park 2

= 184 + 108

= 292

.The measures of the angles of a triangle are in the extended ratio 6: 1: 5. What is the measure of the largest angle?

Answers

9514 1404 393

Answer:

90°

Step-by-step explanation:
