The area of a triangle is 30 square feet. If the height of the triangle is 5 feet, what is the base of the triangle?

Answers

Answer:

150

Step-by-step explanation:

Answer:

12 feet

Step-by-step explanation:

Area of a triangle is A = 1/2 b h

Plug in:

Area = 30

Height = 5

30 = 1/2 (5)b

Divide by 1/2:

30 / 1/2 = 60

60 = 5b

Divide by 5:

60 / 5 = 12

12 = b

Base = 12 feet

Use the elimination method by subtraction to solve for x and then y.
Equation 1 > 2x - 7y = -74
Equation 2 > 3x - 7y = -83
Solve for x and y.
Please and thank you!

Answers

Answer:

Step-by-step explanation:

Both equations have -7y. You can eliminate them by subtracting one equation from the other:

Multiply equation 1 by -1, then add it to equation 2:

-2x + 7y = 74

3x - 7y = -83

———————

x = -9

2x - 7y = -74

2(-9) - 7y = -74

-7y = -56

Y = 8

(x,y) = (-9, 8)

Jamal is making a snack mix that contains only pretzels and nuts. For every ounce of nuts, he will use 2 ounces of pretzels.
How many ounces of pretzels and how many ounces of nuts does he need to make 45 ounces of snack mix?

Answers

Answer:

Pretzels: 30 ounces, Nuts: 15 ounces

Step-by-step explanation:

Trust me.

Number of ounces of nuts = 30

Number of ounces of pretzels = 15

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Jamal is making a snack mix with pretzels and nuts.

And, For every ounce of nuts, he will use 2 ounces of pretzels.

Total number of snake mix = 45 ounces

Now,

Let number of ounces of pretzels = y

Let number of ounces of nuts = x

So, We can formulate;

⇒ x = 2y ... (i)

And, x + y = 45 .... (ii)

Substitute the value of x in equation (ii) , we get;

x + y = 45

2y + y = 45

3y = 45

y = 15

And,

x + y = 45

x + 15 = 45

x = 30

Therefore,

Number of ounces of nuts = 30

Number of ounces of pretzels = 15

We can see that: 7+9 = 16, and 16 is not greater than 18.
