what number needs to be added to 7 and 9 so that the ratio of the first number to the second becomes 4:5?​

Answer: w = -2

Step-by-step explanation:

7w = -14

Divide both sides by 7

w = -2

That was brief but hope it helps!

Answer:

W = -2

Step-by-step explanation:

7W÷7      -14÷7

W= -2

Answer: 32768 or [tex]8^5[/tex].

Step-by-step explanation:

[tex]8^7[/tex]= 8x8x8x8x8x8x8 = 2097152

[tex]8^2[/tex]= 8x8 = 64

                                            Dividing Exponents

When you divide exponents with the same base. You subtract. So in this case, you subtract 7 by 2, (being exponents). The same base is 8. So your subtracting [tex]8^7[/tex] by [tex]8^2[/tex]. Which will get you [tex]8^5[/tex].

                                          Dividing Whole Numbers.

You are going to divide whole numbers. Its pretty self explanatory but I will do the math for you anyways.

64 goes into 2097152, 32768 times. Or we can say,

2097152 divided by 64 = 32768.

So the answer is 32768, or [tex]8^5[/tex].

Answer:

[tex](t,50-t) = \{(10,40),(20,30),(25,25)\}[/tex]

Step-by-step explanation:

Given

[tex]Expression: 50 - t[/tex]

Required

Evaluate when:

[tex]t = \{10,20,25\}[/tex]

When [tex]t =10.[/tex]

The expression is:

[tex]50 - t = 50 - 10[/tex]

[tex]50 - t = 40[/tex]

When t = 20

The expression is:

[tex]50 - t = 50 - 20[/tex]

[tex]50 - t =30[/tex]

When [tex]t = 25[/tex]

The expression is:

[tex]50 - t = 50 - 25[/tex]

[tex]50 - t =25[/tex]

The result is:

[tex](t,50-t) = \{(10,40),(20,30),(25,25)\}[/tex]

100 is the answer okay

Answer:

60 minutes

Step-by-step explanation:

Step 1

We Find and list multiples of each number of minutes that each person walked around the deck until the first common multiple is found. This is the lowest common multiple.

Multiples of 4:

4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68

Multiples of 5:

5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70

Multiples of 6:

6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72

Therefore,

LCM(4, 5, 6) = 60

They would meet again at starting point after 60 minutes

Answer: Rr.3,000

Step-by-step explanation:

The interest is the amount that accrues on a principal that was invested or a cost that was incurred.

It is based on a certain interest rate which in this case is 15%.

The principal is Rr. 20,000.

Interest = Principal * Interest rate

= 20,000 * 15%

= Rr.3,000

Answer:  g = 5/7

=======================================================

Work Shown:

Let's move the -3/7 to the other side, to fully isolate g.

We do so by adding 3/7 to both sides (to undo the subtraction)

[tex]g - \frac{3}{7} = \frac{2}{7}\\\\g - \frac{3}{7}+\frac{3}{7} = \frac{2}{7}+\frac{3}{7}\\\\g = \frac{2+3}{7}\\\\g = \frac{5}{7}\\\\[/tex]

Luckily all of the denominators are the same (7), so we can add the fractions by adding the numerators to place that sum over the common denominator.

Step-by-step explanation:

Answer- 44.60

Step-by-step explanation:

Answer:

Both lines have a slope of 5, therefore they are parallel lines.

Step-by-step explanation:

The equation of line L₁, is y=5x+1 The equation of line L₂ is 2y-10x+3=0 Show that these two lines are parallel.

As we know, the Parallel lines have equal slopes

The slop intercept form is y = mx + c

Where m is the slope and c is the y-intercept.

Consider the line L₁,

y = 5x + 1 is in the slop intercept form where slope m = 5

Now consider the line L₂.

Write L₂, 2y-10x+3=0 into slope-intercept form

[tex]2y=10x-3[/tex]

[tex]y=5x-\frac{3}{2}[/tex]

The slope of the lines L₂ is m = 5.

Since both lines have a slope of 5, therefore they are parallel lines.

Answer:

b.angle 5 and angle 4

Step-by-step explanation:

b.angle 5 and angle 4

Answer:

Step-by-step explanation:

Step-by-step explanation:

Supplementary angles add up to 180°. so,

2x+15 + 3x+5 = 180

5x+20=180

Subtract 20 from both sides

5x=160

Divide both sides by 5

x=32

Plug that into 2x+15, F = 64+15 = 79

for 3x+5, G = 96 +5 = 101
