Write 83 as a sum of tens and ones

Hoochie [10]

Well,

We can see that there are 8 10's and 3 1's. So we can write 8 10's followed by 3 1's and join them with addition symbols.

83 = 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1

Solve for d: 0.5(2d-6)=0.2(4x-10)

Law Incorporation [45]

Answer:d=0.8x+1

Step-by-step explanation:

To solve 0.5(2d-6)=0.2(4x-10)

Open the brackets

We get

d-3=0.8x-2

To make d the subject of formular

d=0.8x-2+3

d=0.8x+1

Which number satisfies the inequality 9h + 15 > 55?

zalisa [80]

When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.

9h + 15 > 55

Subtract 15 from each side: 9h > 40

Divide each side by 9 : <em> h > 40/9</em>

Any number greater than (4 and 4/9) satisfies the inequality.

|x|, if x=10; .3; 0; −2.7; −9

alekssr [168]

Answer:

For $\left | x \right |$ we will have positive values only.

$\left | -2.7 |\right =2.7$

$\left | -9 |\right =9$

Rest are positive so will give positive values out of the modulus function.

Step-by-step explanation:

The absolute value of any number is its positive value only.

As for example $(-2.7)$ and $(2.7)$ both are having equal distance from $0$ in a number line, one on the left other on the right side of the number line but are equidistant from $0$ .

So absolute value of a number is its distance on number line from reference point $0$ .

One by one we will work with all of our question.

$\left | 10 |\right =10$

$\left | 0.3 |\right =0.3$

$\left | 0 |\right =0$

$\left | -2.7 |\right =2.7$

$\left | -9 |\right =9$

So we have to take the positive number out of the modulus function that is also called absolute value.
