HELP ME ASAP for 37 points!! which expression is equivalent to 14.5d+8.5-1/2d+1/2+2.5d
lina2011 [118]

Equivalent expressions are expressions with equal values

The equivalent expression is 16.5d+9

<h3>How to determine the equivalent expression</h3>

The expression is given as:

14.5d+8.5-1/2d+1/2+2.5d

Express the fractions as decimals

14.5d+8.5-0.5d+0.5+2.5d

Collect like terms

14.5d-0.5d+2.5d+8.5+0.5

Evaluate the like terms

16.5d+9

Hence, the equivalent expression is 16.5d+9

How to do multiplication large numbers.
Keith_Richards [23]

Answer:

The main reason to know the multiplication table is so you can more easily multiply larger numbers. For example, suppose you want to multiply 53 x 7. Start by stacking these numbers on top of another, aligning the ones place. Draw a line underneath, and then multiply 3 by 7. Because 3 x 7 = 21, write down the ones digit (1) and carry the tens digit (2) to the tens column:

Next, multiply 5 by 7. This time, 5 x 7 = 35. But you also need to add the 2 that you carried over, which makes the result 37. Because 5 and 7 are the last numbers to multiply, you don’t have to carry, so write down the 37 — you find that 53 x 7 = 371:

When multiplying larger numbers, the idea is similar. For example, suppose you want to multiply 53 by 47. Be sure to align the stacked numbers by the ones place. (The first few steps — multiplying by the 7 in 47 — are the same, so pick up the next step.) Now you’re ready to multiply by the 4 in 47. But remember that this 4 is in the tens column, so it really means 40. So to begin, put a 0 directly under the 1 in 371:

This 0 acts as a placeholder so that this row is aligned properly.

When multiplying by larger numbers with two digits or more, use one placeholding zero when multiplying by the tens digit, two placeholding zeros when multiplying by the hundreds digit

Suppose RS is conjurated to MN. For each of the set of lengths, solve for X, and find the length of each segment.
NeX [460]

If RS is congruent to MN then the value of x in all the parts are 6,4, and 10.

Given RS is congruent to MN.

We are required to find the value of x if RS is congruent to MN.

Congruent lines are those lines whose lengths are equal to each other.

1) RS=x+10, MN=2x+4.

Because the congruent lines have equal lengths so , RS=MN.

x+10=2x+4

x-2x=4-10

-x=-6

x=6

2) RS=3x-2, MN=x+6

Because the length of lines are equal,so RS=MN.

3x-2=x+6

3x-x=6+2

2x=8

x=4

3) RS=5x-10, MN=2x+20

The lengths are equal so RS=MN.

5x-10=2x+20

5x-2x=20+10

3x=30

x=10

Hence if RS is congruent to MN then the value of x in all the parts are 6,4, and 10.
