Answer:
when I worked it out I actually got -1466...
Step-by-step explanation:
Using order of operations you would multiply the 2 by 742, then subtract from left to right. 2 x 742 =1484 and 30 minus that is -1454. Subtracting 12 would give you -1466. I know that's not in the answer choices but that's what I got...
You have to know how the value of one unit corresponds to the value of the other unit. For example you have to know that there are 100 cm in 1 m or 1000 m in 1 km. It's easy in metric measurement system because it's all about multiplying/dividing by 10 or its multiplications. But in American/English system you just have to learn the values.
For example:
1 km = 1000 m = 10000 dm = 100000 cm = 1000000 mm
But:
1 mile = 1760 yards = 5280 feet = 63360 inches
Answer:
10 and 1/5
Step-by-step explanation:
11-4/5=10 and 1/5. x must be 10 and 1/5
Answer:
D. 49p² - 64
Step-by-step explanation:
(7p - 8)(7p + 8)
Solving this requires the 'difference of squares' concept which states;
If (a - b)(a + b)
Then the solution must be a² - b²
Considering (7p - 8)(7p + 8) then the answer is;
(7p)² - 8² = 49p² - 64
