Let her total budget = x

0.45 x = 76.5     Divide by 0.45

0.45 x / 0.45 = 76.5 / 0.45

x = 170 dollars. I'm using a calculator. Are you allowed to do that?

<em>Solution</em><em>,</em>

<em>Let </em><em>the </em><em>ratios </em><em>be </em><em>5</em><em>x</em><em>,</em><em>4</em><em>x</em><em> </em><em>and </em><em>3</em><em>x</em>

<em>Now,</em>

<em>5</em><em>x</em><em>+</em><em>4</em><em>x</em><em>+</em><em>3</em><em>x</em><em>=</em><em>4</em><em>8</em><em>6</em><em>0</em>

<em>or,</em><em>1</em><em>2</em><em>x</em><em>=</em><em>4</em><em>8</em><em>6</em><em>0</em>

<em>or,</em><em>X=</em><em>4</em><em>8</em><em>6</em><em>0</em><em>/</em><em>1</em><em>2</em>

Statement 4(6x+1) +4 =104 reason ?
Murljashka [212]

Answer:

x = 4

Step-by-step explanation:

4(6x+1) +4 =104

            -4     -4

4(6x+1) = 100

distribute

24x + 4 = 100

       -4       -4

24x = 96

x = 4

To check your work, substitute the x value into the equation.

4(6(4)+1) +4 =104

4(25) + 4 = 104

104 = 104

It is correct, one solution.

In a certain Algebra 2 class of 23 students, 11 of them play basketball and 13 of them play baseball. There are 8 students who p
Artemon [7]

Answer:

  9/23

Step-by-step explanation:

Of the 23 students, 9 play both baseball and basketball. The probability of choosing one of those is 9/23.

___

Let A represent basketball, and B represent baseball. Then ...

  P(A or B) = P(A) +P(B) -P(A and B)

Since 8 students play neither sport, we have ...

  1 -8/23 = 11/23 +13/23 -P(A and B)

  15/23 = 24/23 -P(A and B)

  P(A and B) = (24 -15)/23

  P(A and B) = 9/23

WILL MARK BRAINLIEST!! Multiply. −1/2⋅3/4 a)−2/3 b) −3/8 c) 3/8 d)2/3
Rom4ik [11]
<h3>Answer:  B)  -3/8</h3>

Explanation:

When multiplying fractions, we multiply the numerators together, and the denominators are handled separately.

The numerators in this case are -1 and 3. They multiply to -3

The denominators multiply to 2*4 = 8

So that's how we end up with -3/8 as the final answer

This fraction cannot be reduced any further, because 3 and have 8 no factors (other than 1) in common.
