Answer:

3/4

Step-by-step explanation:

1 1/2 can be expressed as an improper fraction 3/2

hence

1 1/2 ÷ 2

= 3/2 ÷ 2

= 3/2 x 1/2

= 3/4

Answer:

The solution to the system of equations becomes:

(x, y) = (7, 12)

Step-by-step explanation:

Given the system of equations

[tex]5x - 3y = -1[/tex]

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

Solving using the Elimination Method

[tex]\begin{bmatrix}5x-3y=-1\\ 2x-y=2\end{bmatrix}[/tex]

Multiply 5x - 3y = - 1 by 2:  10x - 6y = -2

Multiply 2x - y = 2 by 5:  10x - 5y = 10

[tex]\begin{bmatrix}10x-6y=-2\\ 10x-5y=10\end{bmatrix}[/tex]

subtraction operation

[tex]10x-5y=10[/tex]

[tex]-[/tex]

[tex]\underline{10x-6y=-2}[/tex]

[tex]y=12[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}10x-6y=-2\\ y=12\end{bmatrix}[/tex]

Therefore, the value of y = 12

For 10x - 6y = -2 plug in y = 12

10x - 6y = -2

10x - 6(12) = -2

10x - 72 = -2

10x = -2+72

10x = 70

dividing both sides by 10

10x/10 = 70/10

x = 7

Therefore, the value of x = 7

Thus, the solution to the system of equations becomes:

(x, y) = (7, 12)

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Probability (P) is calculated as

P = [tex]\frac{number}{count}[/tex]

Since P(eclair) = [tex]\frac{1}{15}[/tex] and there are 3 eclairs, then original probability before simplification must have been

[tex]\frac{3}{45}[/tex]

meaning the total number of sweets is 45, so

3 + 2x + 6 + x = 45

3x + 9 = 45 ( subtract 9 from both sides )

3x = 36 ( divide both sides by 3 )

x = 12

Then number of humbugs = 2x + 6 = 2(12) + 6 = 24 + 6 = 30

P(humbug) = [tex]\frac{30}{45}[/tex] = [tex]\frac{2}{3}[/tex]

Answer:

 a + b - ( a - ( a-a)) = - 6

Step-by-step explanation:

Explanation:-

Given that a =-5 and b=-6

Given expression

        a + b - ( a - ( a-a))

  =  -5 +(-6)) - ( -5 -(-5-(-5))

  = -5 -6 - (-5 -0)

 =  - 5 - 6 +5

= - 6

Final answer:-

 a + b - ( a - ( a-a)) = - 6

Answer:

Farmer Janet can plant carrots more quickly.

Step-by-step explanation:

If we added 15 more minutes to Farmer Janet's time to equal the same amount as her daughter. We would also have to double the amount of carrots she can plant which totals out to 18 carrots which is 1 more carrot more than her daughter. I hope this helps:)

Answer:

Area = 2x^2 + 14x + 24

Step-by-step explanation:

You could set up an expression (2x + 8) * (x + 3), where you multiply 2x by x, 2x by 3, 8 by x, 8 by 3, and then add them all up. 2x * x  = 2x^2, 2x * 3 = 6x, 8 * x = 8x, and 8 * 3 = 24. 2x^2 + 6x + 8x + 24 = 2x^2 + 14x + 24, so that is your answer.

Answer:

0 because it is in the tens place

Step-by-step explanation:

Answer:

the answer is A

Step-by-step explanation:

5x + 78 + 47= 180

solve for x

x=11

Answer: A) 11

Step-by-step explanation:

there are 180 degrees in a triangle. so, i added 47 and 78 together. that got me 125. i subtracted that from 180, in order to find the remaining angle.

it was 55 degrees, so i divided 55 by 5 in order to see what that was. whatever number that is was going to be x. it turned out to be 11.

answer: $11.40

explanation: turn the percent into a decimal, multiply it by the starting cost, then subtract the product from the starting cost

>> 40% = 0.40

0.40 x 19 = 7.60

19 - 7.60 = 11.40

You paid $11.4 for the shirt.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

A shirt costs $19 you buy it on clearance for 40% off.

You paid,

= 19 - (19 x 40 / 100)

= 19 - 7.6

= $11.4

Therefore, the amount is $11.4.

Answer:

9765625

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

r = 25 ÷ 5 = 125 ÷ 25 = 5

This indicates the sequence is geometric with n th term

[tex]a_{n}[/tex] = a₁[tex]r^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 5 and r = 5 , then

a₁₀ = 5 × [tex]5^{9}[/tex] = 5 × 1953125 = 9765625

Answer:

x > −3

Step-by-step explanation:

Let's solve your inequality step-by-step.

3(x + 2) > x

Step 1: Simplify both sides of the inequality.

3x + 6 > x

Step 2: Subtract x from both sides.

3x + 6 − x > x − x

2x + 6 > 0

Step 3: Subtract 6 from both sides.

2x + 6 − 6 > 0 − 6

2x > −6

Step 4: Divide both sides by 2.

2x / 2 > −6 / 2

x > −3

Answer:

x > −3

Answer:

y minus 8 + 2 less-than-or-equal-to negative 2 + 2

Step-by-step explanation:

Which inequality is equivalent to this one?

y minus 8 less-than-or-equal-to negative 2

y minus 8 + 8 greater-than-or-equal-to negative 2 + 8

y minus 8 + 8 less-than negative 2 + 8

y minus 8 + 2 less-than-or-equal-to negative 2 + 8

y minus 8 + 2 less-than-or-equal-to negative 2 + 2

Take the last option:

y minus 8 + 2 less-than-or-equal-to negative 2 + 2

remove the +2 on each side to get

y minus 8 less-than-or-equal-to negative 2

Answer:

76°

Step-by-step explanation:

two parallel lines intersected by a transversal create several types of angle pairs - some of which are equal to each other, and some of which are supplementary

in this problem, ∠BCD ≅ ∠ BFG because they are 'corresponding'

therefore you can create this equation

x + 26 = 2x - 24

26 = x - 24

x = 50

substitute into '2x-24':  2(50) - 24 = 76
