Answer:

3rd option. The way you do it is just plug in negative x value let's say -8, plug it in then y would be a positive value. So that rules out first two options. Then plug in positive x value, y would be negative.

Answer:

3 more balloons she has popped in the second game.

Step-by-step explanation:

Given that,

Total no. of balloons = 18

Amy popped 2/3 the first game and 5/6 the second game.

Balloons popped in first game = [tex]\dfrac{2}{3}\times 18=12\ \text{balloons}[/tex]

Balloons popped in second game = [tex]\dfrac{5}{6}\times 18=15\ \text{balloons}[/tex]

Difference of balloons popped in first and second game,

= 15-12

= 3 balloons

Hence, 3 more balloons she has popped in the second game.

Answer:

70

Step-by-step explanation:

the red lines mean the two sides are equal

so its an isosceles triangle meaning the two angles other than the 40° one are equal

the inner angles of a triangle must add up to 180

so 180-40 = 2x

140 = 2x

x = 140/2 = 70

Answer:

x=70

Step-by-step explanation:

let unknown angle be a

then,a=x(base angle of an isosceles triangle)

a+x+40=180

x+x=180-40(a=x)

2x=140

x=70

Answer:

Step-by-step explanation:

3 / 1 - 1/2 = 3 / 1/2

when dividing by singular fractions (1/3 1/6 1/29 whatever) just multiply by the denominator so 3 ÷ 1/2 = 6

Step-by-step explanation:

Dimensions of the picture:

Area of the picture:

Scale factor = 2.5

Enlarged picture's area:

Option B is correct

The area of the picture after it is enlarged is 250 inches².

Given that,

The length of the rectangle is labeled 5 inches. The width of the rectangle is labeled 8 inches.

A photographer wants to use a scale factor of 2.5 to enlarge a picture.

Based on the above information, the calculation is as follows:

Here, the dimensions of the picture are 5 in and 8 in

Hence, the area of the picture is,

5 × 8 = 40 in²

Since, Scale factor = 2.5

So, the enlarged picture's area would be,

40 × 2.5 ×2.5

= 250 in²

Answer:

5x<45 Divide both by five which results in the equation looking like this:x<9. On a number line, there would be an open circle on the nine and the arrow would go to the left.

Step-by-step explanation:

The solution set is x<9 of inequality 5x<45.

A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics.

To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

5x<45

divide by 5

x<9

The graph is the shaded region below x =9.

Therefore, the solution set is x<9. And the graph is given.

Answer:

∠1 and ∠5 are pair of corresponding angles

∠1 and ∠8 are pair of alternate exterior angles

∠3 and ∠6 are pair of alternate interior angles.

Step-by-step explanation:

we need to identify the pair of corresponding angles, a pair of alternate exterior angles and a pair of alternate interior angles.

1) Pair of corresponding angles

Angles that are at the same corner at each intersection.

So, ∠1 and ∠5 are pair of corresponding angles

2) Pair of alternate exterior angles

A pair of angles that are on outer side of the two lines but on opposite sides of the transversal.

So, ∠1 and ∠8 are pair of alternate exterior angles

3) Pair of alternate interior angles

A pair of angles that are on inner side of the two lines but on opposite sides of the transversal.

So, ∠3 and ∠6 are pair of alternate interior angles.

Answer:

28.4 miles/gallon

Step-by-step explanation:

to find the answer, you need to find the constant by dividing the miles drove by the amount of gasoline (or the other way around in terms of wording if it is not correct grammar) So you need to do 35.5/1.25 .  FYI I converted the fraction to decimal. The answer is 28.4 miles/gallon.

Answer:

5 of the 7 boxes are 8 inches in height

Step-by-step explanation:

Mathematically;

1 ft = 12 inches

So, 5 ft will measure 5 * 12 = 60 inches

So from what we have ,

We want to combine 8 and 10 inches to give 60 inches total

Let the number of 10 inches be x and the number of 8 inches be y

Mathematically;

x + y = 7 •••••(i)

10x + 8y = 60 ••••(ii)

From equation i, x = 7-y

Put this in equation ii

10(7-y) + 8y = 60

70-10y + 8y = 60

70-60 = 10y-8y

2y = 10

y = 10/2

y = 5
