SOS MSENVJBQJBVKJQBH I NEED HELP- math is way to hard i think im gonna drop out lols 4(5 + 2x) – 5 = 3(3x + 7)
Answer: x= -6 I'm not sure about this though.
Step-by-step explanation:
Answer:
[tex]4(5 + 2x) - 5 = 3(3x + 7)[/tex]
[tex]20 + 8x - 5 = 9x + 21[/tex]
[tex]15 + 8x = 9x + 21[/tex]
[tex]9x + 21 = 15 + 8x[/tex]
[tex]9x - 8x = 15 - 21[/tex]
[tex]x = - 6[/tex]
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?
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

Answer:
(x, y) → (x - 2, y + 8)m∠8 = 65°Step-by-step explanation:
Q1The translation is the difference between two corresponding points:
-2 - 0 = 26 - (-2) = 8Correct option is C
(x, y) → (x - 2, y + 8)Q2∠8 and 115° are supplementary and sum to 180°
m∠8 = 180° - 115° = 65°

A designer jacket was purchased for $140. Since it was purchased, the price has decreased by 18%. What is the price now?
Answer:

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

what is the solution to the system of equations? please help im struggling really bad ):
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
B-30.45=95.28 what is the answer
Answer:
[tex]B = 125.73[/tex]
Step-by-step explanation:
Step 1: Add 30.45 to both sides
[tex]B - 30.45=95.28[/tex]
[tex]B +(- 30.45 + 30.45)=(95.28 + 30.45)[/tex]
[tex]B = 125.73[/tex]
Answer: [tex]B = 125.73[/tex]
.The measures of the angles of a triangle are in the extended ratio 6: 1: 5. What is the measure of the largest angle?
9514 1404 393
Answer:
90°
Step-by-step explanation:
The largest angle is 6 of the 6+1+5 = 12 ratio units, so is 6/12 = 1/2 of the total number of degrees in a triangle.
The largest angle is 1/2(180°) = 90°.
