7x-8x+4=5x-2 solve for x

Answers

Answer 1

Answer: 7x - 8x + 4 = 5x - 2

7x - 8x - 5x = -2 - 4

-6x = -6

x = 1

Answer 2

Answer: $7x-8x+4=5x-2 \n 4+2=5x-7x+8x \n 6=6x \n 6/6=x \n 1=x$

Answers

The answer is (1,-10)

You solve this by equating the two equations:
-x2 -5x -4 = -x2 +9x -18
-14x = -14
x =1

You then substitute 1 to either of the equations to find y:
y = -(1)2 -5(1) -4
y = -10

Therefore, the solution is (1,-10)

Answers

Answer:

She made $117.25

Step-by-step explanation:

Consider the provided information.

The price of marigold(M) is $5.75.

The price of daisy(D) is $6.25.

The price of roses(R) is $2.50.

The price of Lilies(L) is $3.75

She sold 8 marigold flats and 10 daisy flats. An hour before closing, she sold 5 bunches of roses at half price and 2 bunches of lilies for 1/3 of the price

Total money Paloma made = $8M+10D+5* (R)/(2)+2* (L)/(3)$

Now substitute the respective value

Total money Paloma made = $8(5.75)+10(6.25)+5* (2.50)/(2)+2* (3.75)/(3)$

Total money Paloma made = $46+62.5+6.25+2.5$

Total money Paloma made = $117.25$

Hence, she made $117.25

What is 400 feet in 52.4 seconds

Answers

To find out how many feet in 1 second we have to divide;-

52.4 ÷ 400 = 0.131
0.131 feet per sec.

CHECK OUR WORK:-

0.131 × 400 = 52.4
We were RIGHT!!!

So, 0.131 feet per second.

Hope I helped ya!! xD

0.131 feet per second is the answer

to prove it , 0.131*400=52.4 before that it's 52.4/400=0.131

i hope this helps

Debbie is making an abstract painting with two triangles. The dimensions of the painting are shown below:Two triangles share the same height of 8 inches. One triangle has a base of 6 inches and the other is 10 inches.

The total area of the two triangles is _____ square inches.

Answers

Debbie's abstractpainting are two in numbers both having the same height. since we know the area of a triangle to be

Area = 1/2*Base*Height

Total area =Area of Triangle A+ Area of Triangle B

= 24+40

=64 square inches

Given data

Both Triangles share the same height = 8 inches

For Triangle A

Base = 6 inches

Area = 1/2 Base*Height

Area = 1/2*8*6

Area = 24 square inches

For Triangle B

Base = 10 inches

Area = 1/2 Base*Height

Area = 1/2*8*10

Area = 40 square inches

Total = 24+40

Total = 64 square inches

The surface of the triangle count formula
A = b*h*1/2
A - area
b - base
c - height
The first triangle
A₁ = b₁*h = 6in * 8in *1/2= 24in²

The second triangle
A₂ b₂*h = 10in * 8in*1/2 = 40in²

The total area of the two triangles is 24in² + 40in² = 64 square inches
