Answer: b = 90

Step-by-step explanation:

Full triangle is 180

5 + 4 = 9 + 1 (the smallest angle)

180 ÷ 10 = 18

First and smallest angle is 18

p= 18

Second angle is 72

18 × 4 = 72

Thrid angle is 90

18 × 5 = 90

b = 90

18 + 72 = 90 + 90 = 180

Answer:

Proportional

Step-by-step explanation:

It is proportional because the relationship between the quantities are constant. If we look at the first two points, 10-5 / 2-1. = 5       If we look at other points, they will all equal 5. This means it is constant and therefore proportional.

Step-by-step explanation:

80 times 2 is 160

Therefore, 100 times 2 is 200

You multiply the denominator and numerator by the same number.

Answer:

Gina spent more money, she spent 2 more cents than Amy.

Step-by-step explanation:

Gina:     1.38x2=$2.76    1.38/2=69 cents

2.76+69= $3.45

Amy:     0.98x3=$2.94   0.98/2=49 cents

2.94+49= $3.43

You can divide your diagram into one-unit (feet, cm, miles) segments vertically and horizontally if you want to visualize how the area measurement will look. Multiply the length of your rectangle by the width.

Answer: cant really see the words and my laptop makes it really  blurry already

Step-by-step explanation:

Answer:

x/3.5h = -$1.4

So, x = -$1.4 * 3.5h

= -$4.9

Step-by-step explanation:

Since your losing $1.4 every hour, the 1.4 is supposed to negative.

Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours

and get  -$4.9.

Step-by-step explanation:

7 - (2m - 5)

Hey there!

In order for us to find out which one is equivalent to 5 – 2m , we can go through all of your options to see which one gives us that!

“Equivalent to 5 – 2m”

Option A.

7 – 2(m + 1)

Distribute

7 – 2(m) + 2(1)

7 – 2m + 2

COMBINE LIKE TERMS

7 – 2 = 5

Option Answer: 5 – 2m

Option A can be a possible ANSWER ✅

Option B.

7 - (2m - 5)

DISTRIBUTE

7 – 2m + 5

COMBINE LIKE TERMS

7 + 5 = 12

–2m = –2m

Option Answer: –2m + 12

Option B CAN’T possibly be your ANSWER ❌

Option C.

7 - 2(m - 2)

DISTRIBUTE

7 - 2(m) + (–2)(–2)

7 – 2m + 4

COMBINE YOUR LIKE TERMS

7 + 4 = 11

–2m = –2m

Option answer: –2m + 11

Option C. CANT possibly be your ANSWER ❌

Now that we have went through ALL of your choices, this leaves “Option A” as your answer

Answer: Option A). 7 - 2(m + 1) ☑️

Answer:

1. 0,0

2. negative 1

Step-by-step explanation:

It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

Answer: No, the graph does not show a proportional relationship.

Step-by-step explanation:

Proportional relationships have to start at zero, and have a straight line.

Even though the graph has a straight line, it does not start at zero and therefore is not proportional.

I believe its -5 1/4
