Answer: 109 cm^3
Step-by-step explanation:
4 x 7 = 28
28/2 = 14 cm^3
4 x 4 = 16 cm^3
4 x 15 = 60
60/2 = 30 cm^3
4 x 7 = 28 cm^3
7 x 6 = 42
42/2 = 21 cm^3

Answer:
1. 4.5x - 151.89
2. -2x + 375
Step-by-step explanation:
1.
Start with -$126.89
Small deposit: x (add)
Large deposit: 3.5x (add)
Withdrawal: $25 (subtract)
-126.89 + x + 3.5x - 25 =
= -151.89 + 4.5x
= 4.5x - 151.89
Answer: 4.5x - 151.89
2.
Start with $350
Small withdrawal: x (subtract)
Large withdrawal: x + 50 (subtract)
Deposit: $75 (add)
350 - x - (x + 50) + 75 =
= 350 - x - x - 50 + 75
= -2x + 375
Answer: -2x + 375

What is the solution to the system of linear equations below? 2/5x−y=6 −2x+5y=−30 Select one: A. (-13, 14) B. (-5, -8) C. no solution D. infinitely many solutions
Answer:
D. Infinitely many solutions
Step-by-step explanation:
[tex]-\frac{2}{5}x-y=6 | -2x+5y=-30[/tex]
1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding [tex]\frac{2}{5}x[/tex] to both sides.
Like this: [tex]\frac{2}{5}x-\frac{2}{5}x-y=6-\frac{2}{5}x[/tex]
ending up with [tex]y=6-\frac{2}{5}x[/tex]
2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.
Like this [tex]\frac{-y=6-\frac{2}{5}x }{-y}[/tex]
Ending with [tex]y=-6+\frac{2}{5}x[/tex]
3.Now, we can plug the expression [tex]-6+\frac{2}{5}x[/tex] into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.
Like this [tex]-2x+5(-6+\frac{2}{5}x)=-30\\ -2x-30+2x=-30\\[/tex]
4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.

Write and solve the equation that represents the sentence below.
The product of 18 and a number is 109.8.
Which statements are correct? Check all that apply.
It can be solved by using the division property of equality.
It can be solved by using the multiplication property of equality.
The equation should be StartFraction x Over 18 EndFraction = 109.8.
The equation should be 18 x = 109.8.
The answer is 6.1.
The answer is 1,976.4.
Answer:
The equation should be 18x = 109.8
The answer is 6.1
Step-by-step explanation:
The word "product" tells you that 8 and x are being multiplied to give 109.8.
If you use that equation to solve for x by dividing 109.8 by 18, you will get 6.1.

Step-by-step explanation:
Write the equation of the line in slope-intercept form using y=mx+b
Answer:
y= -100 x= 100
Step-by-step explanation: The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m(x-a) is essentially different from the other two forms, and means slope m and x-intercept (instead of y-intercept) a.
