There are 90 calories in a 3/4 cup serving of cereal.
How many calories are in 1 cup?
How many calories are in 6 cups?
90
3/4
=1
=6

Answers

Answer:

120 calories in 1 cup, 720 in 6 cups

Step-by-step explanation:

I divided 90 by 3 to get 1/4 cup and then multiplied it by 4 to get for one cup. From there I multiplied by 6

Answer:

1 cup=120 calories    6 cups=720 calories

Step-by-step explanation:

We know that there are 90 calories in 3/4 of a cup and we can figure out that 30 calories are in each 1/4 of a cup because 90 divided by 3 equals 30 then just add 30 calories to 90 and get 120.  Finally just do 120 times 6 and get 720 .

Draw the straight line y = 2x - 3

Answers

Answer:

See the picture down below

Step-by-step explanation:

When you are drawing a line you should first mark the y-intercept, which in this case it's (0,-3) because the the b in the equation is -3. Then we will go 2 units up then 1 unit right. Keep going until you've run out of room. Then draw the line going through all the points.

The graph of  y = 2x - 3 is attached and slope of the given graph is 2.

What is Straight Line?

A line is an infinitely long object with no width, depth, or curvature.

y=mx+b is the standard form of a line, where m is slope and b is the y intercept.

When a line passes through (x₁, y₁) and (x₂, y₂) then slope

m=y₂-y₁/x₂-x₁

The given equation is  y = 2x - 3

When we compare this with standard form

m is 2 which is slope.

To draw graph we have to find few values of x and y.

If x=0,

then y=-3

(0, -3) is one point in the line.

If x=1

then y=-1

(1, -1) is second point in the line.

if x=2

y=1

if x=3

then y=3

if x=4

then y=5

Hence, the graph of  y = 2x - 3 is attached and slope of the given graph is 2.

correct. -9x2-30x-25

Answers

Answer: Rico is right.

(-1)(3x + 5)²

Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.

Solve for [x]. The pair of polygons are similar. The scale factor from A to B is 9:10​

Answers

Answer:

9

Step-by-step explanation:

if scale factor is 3/5, then

(x+12):35=3:5, ⇒

The value of x in the pair of polygons is 19 .

Given,

Two similar triangle .

Now,

The side of one triangle is 3x -12 .

The side of other triangle is 50 .

As the triangle are similar then the ratio of corresponding sides will be equal to the scale factor .

So,

3x - 12/ 50 = 9/10

3x - 12 = 45

3x  = 57

x = 19

Thus the value of x is 19 .
