Answer:

7/5 or 1 2/5

Step-by-step explanation:

I made the proper fractions into improper fractions.

Ex : 3 1/5 as an improper fraction is 16/5

Ex : 1 4/5 as an improper fraction is 9/5

16/5 - 9/5 = 7/5 or 1 2/5

Solve the equation for x by graphing -2x + 3 = -3(-x) - 2
adoni [48]

Answer:

  x = 1

Step-by-step explanation:

There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.

__

Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.

  (-2x +3) -(-3(-x) -2) = 0

A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...

  -5x +5 = 0

So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.

castortr0y [4]

Answer:$ 66.5

Step-by-step explanation:

Using ordinary Annuity formula

FV=\frac{P\times \left [ \left ( 1+r\right )^n-1\right ]}{r}

FV=future value=$24000

P=monthly payment

r=rate of interest =5.4%

for monthly r=\frac{5.4}{12}=0.45%

n=number of payments  =9\times 12=108

24000=\frac{P\times \left [ \left ( 1+0.0045\right )^{108}-1\right ]}{0.0045}

108=P\times (1.6240)

P=$ 66.501

sop monthly deposit of  $ 66.5 is required.

WILL GIVE BRAINLEIST DUE AT 9:45 P.M. PLS HURRY SUPER EASY.
Lemur [1.5K]

Answer:

c = 2

Step-by-step explanation:

Since 16 is over the variable c, first multiply both sides by c so the variable is not in the denominator of the fraction.

16/c(c) = 8(c)

16 = 8c           Next, divide both sides by 8 to solve for c.

c = 2
