Answer:

D. Christy saved $3 per week more than Kevin.

Step-by-step explanation:

We already know how much Christy saves per week, because of the equation y = 26x. She saves $26 per week.

To find Kevin's per week savings, divide y by x. I'll do (6, 138) as an example.

138 / 6

What multiple of 60 is closest to 138 without going over. That's 120.

138 - 120 = 18

Now we know the constant (k) is greater than 20.

18 / 6

6 goes into 18 three times.

20 + 3 = $23 per week.

$23/week is less than $26/week, so to say Kevin earned more than Christy in one week is wrong. As a result, A and C are out.

Now subtract 23 from 26 to get a $3 per week difference, which is D.

Answer:

19 is 38x - 3y - 34

20 would be yes

Answer:

x = 2/11

Step-by-step explanation:

1 ÷ 11/2 = x

1 · 2/11 = x (Used the opposite reciprocal and changed to multiplication. This is the same as dividing with the original fraction.)

2/11 = x

Answer:

[tex]1 \div \frac{11}{2} = x \\ \frac{1}{ \frac{11}{2} } = x \\ x = \frac{2}{11} \\ thank \: you[/tex]

Answer:

Step-by-step explanation:

it should be  (x+3)2=5

xx2=2x+5=5

5-5=0

x=2

Answer:

(x+3)2=5

2(x+3)=5

2x+2x3=5

2x+6=5

(2x+6)+(-6)=5+(-6)

2x+6-6=5-6

2x=-1

2x/2=-1/2

x=-1/2

Answer:

-0.25

Step-by-step explanation:

-8= 2/x

multiply both sides by x -> -8x =2

divide both sides by -8 -> x=2/-8

Ans= -1/4 = -0.25

Answer:

Please check the explanation.

Step-by-step explanation:

Given the verbal expression

''Thirteen less than twice the sum of a number and six is 47''.

Let us break down the verbal expression into an algebraic equation

And finally

Thirteen less than twice the sum of a number and six is 47:

2n+6-13 = 47

Therefore, the equation is:[tex]2n+6-13 = 47[/tex]

Solving the algebraic expression

solving the equation for 'n'

[tex]2n+6-13 = 47[/tex]

[tex]2n-7=47[/tex]

Add 7 to both sides

[tex]2n-7+7=47+7[/tex]

Simplify

[tex]2n=54[/tex]

Divide both sides by 2

[tex]\frac{2n}{2}=\frac{54}{2}[/tex]

Simplify

[tex]n=27[/tex]

Answer:

107

Step-by-step explanation:

7 + (5^2) x4

= 7 + 25x4

= 7 + 100

= 107

Answer:

We conclude that:

Step-by-step explanation:

From the given right-angled triangle,

Using the trigonometric ratio,

cos y = adjacent / hypotenuse

substituting adjacent = 5, hypotenuse = 15

cos y = 5/15

cos y = 1/3

y = arc cos (1/3)

y = 70.53°

Therefore, we conclude that:

Answer:

3.272727

Step-by-step explanation:

6^2/(3+9)

= 6^2/(11)

= 36/(11)

= 3.272727

Answer:

C) 10/100

Step-by-step explanation:

1/10

To change it into a different fraction we can multiply, and since we want it to get the denominator to 100, we multiply by 10, because 10 x 10 = 100.

1 x10 10

- -

10 x10 100

Answer:

After two days, 240 degrees was water.

Step-by-step explanation:

24 hours = 1 day

72 hr/24 hr = 3 days

Therefore, one full rotation takes 3 days.

1 rotation = 360 degrees

360 degrees/ 3 days = 120 degrees per day

120 degrees x 2 days = 240 degrees

240 degrees was watered after two days

Answer:

AAA Similarity

Step-by-step explanation:

Given:

Triangles ABC and DBE

Required

Which postulate shows ABC and DBE similarity

From the question, we understand that the following transformation were done on ABC

It should be noted that, when a triangle (e.g. triangle ABC) is rotated, the length of the sides and angle measurements remain unchanged.

However, when this triangle is dilated, the sides of the triangle change, but the angles remain unchanged.

Having said that,

When ABC is rotated and dilated to form DBE, we have:

[tex]\angle A = \angle D = a[/tex]

[tex]\angle B = \angle B = b[/tex]

[tex]\angle C = \angle E = c[/tex]

[See Attachment]

Hence, the postulate that answers this question is AAA (Angle-Angle-Angle).

Answer:

The value of x is 3

The value of m is 5.25

The value of a is 1.75

Step-by-step explanation:

I attached the picture with labels to can solve

In the 2 Δs ADE and ACF

∵ DE // CF

∴ m∠ADE = m∠ACF ⇒ corresponding angles

∴ m∠AED = m∠AFC ⇒ corresponding angles

→ By using the AA postulate of similarity

∴ The two triangles are similar

∴ Their corresponding sides have the same ratio

∴ [tex]\frac{AD}{AC}[/tex] = [tex]\frac{EA}{FA}[/tex] = [tex]\frac{DE}{CF}[/tex]

∵ AD = AB + BC + CD

∵ AB = 3, BC = 6, CD = x

∴ AD = 3 + 6 + x

∴ AD = 9 + x

∵ AC = AB + BC = 3 + 6

∴ AC = 9

∵ AE = AG + GF + FE

∵ AG = 4, GF = 8, FE = 4

∴ AE = 4 + 8 + 4

∴ AE = 16

∵ FA = AG + GF = 4 + 8

∴ FA = 12

∵ DE = 7 and CF = m

→ Substitute them in the ratio above

∴ [tex]\frac{9+x}{9}[/tex] = [tex]\frac{16}{12}[/tex] = [tex]\frac{7}{m}[/tex]

→ By using cross multiplication with the first 2 fractions

∵ 12 × (9 + x) = 9 × 16

∴ 12(9) + 12(x) = 144

∴ 108 + 12x = 144

→ Subtract 108 from both sides

∴ 108 - 108 + 12x = 144 - 108

∴ 12x = 36

→ Divide both sides by 12 to find x

∴ x = 3

→ By using cross multiplication with the second 2 fractions

∵ 16 × m = 12 × 7

∴ 16m = 84

→ Divide both sides by 16

∴ m = 5.25

In the 2 Δs ABG and ACF

∵ BG // CF

∴ m∠ABG = m∠ACF ⇒ Corresponding angles

∴ m∠AGB = m∠AFC ⇒ corresponding angles

→ By using the AA postulate of similarity

∴ The two triangles are similar

∴ Their corresponding sides have the same ratio

∴ [tex]\frac{AB}{AC}[/tex] = [tex]\frac{GA}{FA}[/tex] = [tex]\frac{BG}{CF}[/tex]

∵ AB = 3 and AC = 9

∵ GA = 4 and FA = 12

∵ BG = a and CF = m = 5.25

→ Substitute them in the ratio above

∴ [tex]\frac{3}{6}[/tex] = [tex]\frac{4}{12}[/tex] = [tex]\frac{a}{5.25}[/tex]

→ By using cross multiplication with the second 2 fractions

∵ 12 × a = 4 × 5.25

∴ 12a = 21

→ Divide both sides by 12 to find a

∴ a = 1.75

x + (x + 2) + 38 = 180

2x + 40 = 180

2x = 140

x = 70
