−2x < 10

⋅ (−2x) > 10 ⋅

x > −

How many milligrams are in

4 grams?

FRONT

4,

Explanation:

There are 1,000 milligrams in every

gram, so to convert grams to

milligrams, multiply by 1,000, or

move the decimal point three places

to the right: 4 × 1,000 = 4,000.

Convert 500 milliliters to

liters.

FRONT

0.5 liter

Explanation:

There are 1,000 milliliters in every

liter, so to convert milliliters to liters,

divide by 1,000, or move the decimal

What is the total estimate

obtained by adding 1.

mL, 0.45 mL, and 1.47 mL

together after rounding

each of the amounts to an

appropriate number of

places?

FRONT

3.5 mL

Explanation:

Given that the decimal portion of

each value is relatively substantial,

rounding the amounts to the nearest

whole number is inappropriate

because the result (2) is too small,

close to half the value of the actual

sum (3.41). However, rounding the

measurements to the nearest tenth

(1.5 mL, 0.5 mL, and 1.5 mL) results

in an estimated sum of 3.5 mL, which

is much more accurate.

Solve

2 + 5(4– 2 ) – 2 ⋅ 6 =

3

FRONT

Explanation:

The rules governing the order in

which arithmetic operations must be

performed (i.e., parentheses;

exponents; multiplication and

division, in order; and addition and

subtraction, in order) are abbreviated

using the acronym PEMDAS, which

can in turn be remembered using the

acrostic: P lease E xcuse M y D ear
