Over [174]

Answer:

$450

Step-by-step explanation:

We know that the washer costs $51 more dollars than the dryer.

The washer costs x+51

The dryer costs x

So to simplify this we can do this equation:

2x+51=951

Substitute and simply the equation, and you should get this:

2x=900

x=450

Hope this helps! :)

PLEASE HELP I WILL MARK THE BRAINLIEST
-BARSIC- [3]

Given: lines l and m are parallel, and line t is a transversal.

angle pair result/justification

1 and 2 are equal (vertical angles)

6 and 8 are equal (corresponding angles)

1 and 4 are equal (alternate exterior angles)

4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)

Note:

alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.

If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)

If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)

Arisa [49]

Answer: 56.64%

Step-by-step explanation:

Given: Previous amount of flour = 2.26 kilograms

By the end of the baking session, amount of flour = 0.98 kilograms

Decrease in amount = 2.26-0.98 = 1.28  kilograms

Percent decrese = \dfrac{\text{decrease in amount }}{\text{previous amount}}\times100

=\dfrac{1.28}{2.26}\times100\approx56.64\%

Hence, the percent decrease in the amount of flour = 56.64%
