mylen [45]

Answer:

x = 35 degrees.

Step-by-step explanation:

(x\°) + (20+x) \°=90\°

want to solve for solve for x

2x = 90 - 20

2x = 70

x = 70 / 2

x = 35 degree

Which equations could you use the division property of equality to solve?

disa [49]

Answer:

2.35y = 4.70

4 = 10w

55x = 111

Step-by-step explanation:

Hi, the division property of equality states that if we divide both sides of an equation by a non-zero number, the equality remains. (Both sides remain equal).

So, the equations that we have to use the division property of equality to solve are:

2.35y = 4.70

Dividing both sides by 2.35:

2.35y /2.35= 4.70/2.35

y= 2

4 = 10w

4/10=10w/10

0.4=w

55x = 111

55x/55 =111/55

x = 111/55

What is the product of 1.7 × 10−13 and 3.5 × 1025?

kkurt [141]

ANSWER

$3.95 \times {10}^{12}$

EXPLANATION

The first number is

$1.7 \times {10}^{ - 13}$

The second number is

$3.5 \times {10}^{25}$

The product of the above two numbers is
$1.7 \times {10}^{ - 13} \times 3.5 \times {10}^{25}$

We regroup the numbers to obtain,

$(1.7 \times 3.5) \times {10}^{ - 13} \times {10}^{25}$

We now multiply out the expression in the bracket to obtain,

$3.95 \times {10}^{ - 13} \times {10}^{25}$

Recall also that,

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this property to obtain,

$3.95 \times {10}^{ - 13 + 25}$

This finally simplifies to,

$3.95 \times {10}^{12}$

Therefore the correct answer is D.
