Answer:

a=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4a+1−a=19

(4a+−a)+(1)=19 (Combine Like Terms)

3a+1=19

Step 2: Subtract 1 from both sides.

3a+1−1=19−1

3a=18

a=18/3

a=6

Answer:

Triangle b = 4, h = 7

Step-by-step explanation:

Rectangle area = L*W

Triangle area = (B*H)/2

Rectangle/2 = Triangle

If you want triangle to = rectangle, then rectangle*2/2

Rectangle = 4*3.5 = 14

Triangle = 4*7 = 28/2 = 14

Answer:

6 phones and 18 accessories

Step-by-step explanation:

12P + 3.50A = 135

A = 12 + P

12P + 3.50(12 + P) = 135,

12P + 42 +3.50P = 135

15.50P = 93

P = 6 phones

A = 12 + 6 = 18 accessories

Answer:

Holly has 20 quart of potato salad left.

Step-by-step explanation:

Holly has 20 quart of potato salad because she originally has 46 quart of potato but gave her friend 26, subtracting 26 from the original amount of quart of potato she had.

Answer: c = [tex]\sqrt{89}[/tex]

8² + 5² = c²

64 + 25 = c²

[tex]\sqrt{89}[/tex] = [tex]\sqrt{c^{2} }[/tex]

[tex]\sqrt{89}[/tex] = c

The length of the third side is 9.4.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

Applying Pythagorean theorem.

Third side = x

x² = 8² + 5²

8 x 8 = 64 and 5 x 5 = 25

So,

x² = 64 + 25

x² = 89

x = √89
x = 9.4333

Rounding to the nearest tenth

x = 9.4

Thus,

The length of the third side is 9.4.

Answer:

  2x -1

Step-by-step explanation:

The perimeter is the sum of the side lengths.

  P = 6 + (x -4) + (x -3)

  P = 2x -1 . . . . . . collect terms

The perimeter is 2x -1.

Additional comment

There is nothing in the problem statement that suggests this is a right triangle. Without knowing at least one angle, we cannot solve for a numerical value for the perimeter. The problem title suggests we're to leave the result in polynomial form.

Answer: 18 miles.

Step-by-step explanation:

We can think on this as a triangle rectangle, where one cathetus is 12miles, and the other cathetus is 5 miles. (so the vertex of the triangle rectangle are Annie's house, the school, and the store)

The path that Annie would do is:

From her house to the store (so she drives 5 miles)

And from the store to the school, so here she drives through the hypotenuse of the triangle rectangle.

Then we need to find the length of this triangle rectangle.

We know that the square of the hypotenuse is equal to the sum of the squares of the cathetus, then:

H^2 = (12mi)^2 + (5mi)^2

H = √( (12mi)^2 + (5mi)^2) = 13mi

Then she first drives 5 miles from her house to the store, and then drives 13 miles from the store to the school, then the total distance that she drives is:

5 miles + 13 miles = 18 miles.

Answer:

31) They divided by 100, they're suppose to times 0.86 by 100 instead, which will be 86%

33) 0.34 x 100=34%

35) we do the inverse to turn it back into

a decimal which will be 0.36

[tex] \frac{36}{100} = \frac{18}{50} = \frac{9}{25} [/tex]

36) 16.24÷100=0.6424

[tex] \frac{16.24}{100} = \frac{8.12}{50} = \frac{4.6}{25} [/tex]
