Answer:

[tex] \frac{x}{3} + 7 = 10 \\ \frac{x}{3} = 10 - 7 \\ \frac{x}{3 } = 3 \\ x = 3 \times 3 \\ x = 9 \\ thank \: you[/tex]

Answer:

x=9

Step-by-step explanation:

x/3 +7 = 10

Subtract 7 from each side

x/3 +7-7 = 10-7

x/3 = 3

Multiply each side by 3

x/3*3 = 3*3

x=9

Answer:

42

Step-by-step explanation:

S1 let a and b be the digits of the number

so a 2 digit number cab written as - 10×a + b

eg - 68 as 6×10 + 8

S2 ) according to ques

a + b = 6    - eqn 1

(10×a + b) - (10×b + a) = 18

9×a - 9×b = 18

a - b = 2   - eqn 2

S3)from eqn 1 and eqn 2

we get a = 4 and b = 2

hence number is 42

Answer:

9.2 wheels per car.

Step-by-step explanation:

This is because if you divide 184/20, you get 9.2

Answer: i'll answer that if you don't mind the answer is 9.2

Step-by-step explanation: 184 divided by 20 = 9.2 and 9.2 x 20 = 184 thank you :)

answer is option D

because you can divide them like

[tex] \frac{2}{10} = \frac{1}{5} \\ \\ \frac{4}{20} = \frac{1}{5} \\ \\ \frac{6}{30} = \frac{1}{5} \\ \\ \frac{8}{40} = \frac{1}{5} [/tex]

so the option is D

Answer:

x = 20

Step-by-step explanation:

46 x + 322 = 1242

46x = 920

x = 20

Answer:

x ≥ 15

Step-by-step explanation:

first we will subtract 10 from both sides

we get x/3 ≥ 5

then we will multiply both sides by 3

and final answer will be x ≥ 15

Answer:The solution is in the attached file below

Step-by-step explanation:

hi <3

84 + 4m = 276

subtract 84 from both sides:

4m = 192

divide both sides by 4:

m = 192/4 = 48

hope this helps :)

Hey there!

84 + 4m = 276

➡️ 4m + 84 = 276

SUBTRACT 84 to BOTH SIDES

4m + 84 - 84 = 276 - 84

CANCEL out: 84 - 84 because that gives you 0

KEEP: 276 - 84 because that helps solve for the m-value

276 - 84 = 192

NEW EQUATION: 4m = 192

DIVIDE 4 to BOTH SIDES

4m/4 = 192/4

CANCEL out: 4/4 because that gives you 1

KEEP: 192/4 because that helps you get the m-value

NEW EQUATION: m = 192/4

SIMPLIFY ABOVE AND YOU HAVE YOUR ANSWER

m = 48

Therefore, your answer is: m = 48

Good luck on your assignment and enjoy your day!

Answer:

Option(A) [tex]4^{\frac{5}{8}}[/tex] is equivalent to [tex]$\frac{4^{\frac{7}{3}}}{4^{\frac{1}{4}}}$[/tex]

Step-by-step explanation:

Given:

[tex]$\frac{4^{\frac{7}{3}}}{4^{\frac{1}{4}}}$[/tex]

To simplify the expression

Using the exponent rule,

[tex]$\frac{x^{a}}{x^{b}}=x^{a-b}$[/tex]

[tex]$\frac{4^{\frac{7}{3}}}{4^{\frac{1}{4}}}$[/tex][tex]=4^{\frac{7}{8}-\frac{1}{4}}[/tex]

[tex]=4^{\frac{5}{8}}[/tex]

The correct answer option is (A) [tex]4^{\frac{5}{8}}[/tex]

Answer:

x = 14

Step-by-step explanation:

Since the triangles are similar then corresponding sides are in proportion, that is

[tex]\frac{15}{x-4}[/tex] = [tex]\frac{12}{8}[/tex] ( cross- multiply )

12(x - 4) = 120 ( divide both sides by 12 )

x - 4 = 10 ( add 4 to both sides )

x = 14

Answer:

In mathematics, a transformation is a function f (usually with some geometrical underpinning) that maps a set X to itself, i.e. f : X → X. In other areas of mathematics, a transformation may simply refer to any function, regardless of domain and codomain.

Answer:

3,6,9,12 is not geometric seuence

Step-by-step explanation:

Step-by-step explanation:

that back and forth between the different scales is the only task challenge. you need to focus to not mix things up.

so if I understand correctly, we should use the conversion rate of 1 kg = 2.2 pounds.

she should add 1 quart of water to every 26.7 pounds of concrete mix.

80 kg = 80×2.2 pounds = 176 pounds.

we need as many quarts of water as there are units of 26.7 pounds in 176 pounds.

176/26.7 = 6.5917603... quarts of water needed.

that would be rounded 6.6 quarts of water.

Answer:

∠ WOT = 85

Step-by-step explanation:

To find the measure of ∠WOT

we know that ∠UOV is 180 in the pic

so by letting ∠WOT = x

∠UOT + ∠WOT + ∠WOV = 180

30 + x + 65 = 180

95 + x = 180

x = 180-95

x = 85

so ∠ WOT = 85

Answer:#1 is D

Step-by-step explanation:angles must equal 180 and yk that the angle under e is 39 so 180-39 =141
