Answer:

-7

Step-by-step explanation:

Let's try getting rid of the numbers to isolate the x.

Add x on both sides to get rid of the x on the right side and to get 2x on the left side. This leaves us with 15.3 + 2x = 1.3

Subtract 15.3 on both sides to get rid of the 15.3 on the left side.

This would leave us with 2x = -14

Divide 2 on both sides to isolate the x.

The answer is x = -7

If an instrument measures in units of 10, then any value between which two values would be measured as 80?

enyata [817]

Answer:

The answer is 75 and 85.

Step-by-step explanation:

If the instrument measures in units of 10, then the measurement could be 5 units on either side of 80 (80 − 5 = 75, 80 + 5 = 85). Any value between 75 and 85 would be measured as 80.

What is the length of the side a ?<br><br> A=

vodka [1.7K]

Answer:

$a = 5$

Step-by-step explanation:

Notice that $\triangle CDB$ is a right triangle where its hypotenuse is $\overline{CB}$ . We can also see that $a = CB$ . For this we must use the Pythagorean Theorem.

Recall:

The Pythagorean Theorem states that if you have a right triangle, the principal square root of the sum of the squares of each leg is the length the hypotenuse.

We can see that $CD = 3$ and $DB = 4$

$a = \sqrt{CD^2 +DB^2} \\ a = \sqrt{3^2 +4^2} \\ a = \sqrt{9 +16} \\ a = \sqrt{25} \\ a = 5$
