Answer:
u just expand the brackets out and make a linear equation to solve from there
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
Let n be unknown divisor and a be the same remainder, then
Subtract a from all equalities:
Subtract them:
The greatest number is 6. When you divide numbers 63, 45, 69 by 6, you'll get remainders 3, 3, 3, respectively.
Answer: Choice C
The pink equation is y = 2x-3
The yellow equation is y = -2x+1
Notice how the pink equation crosses the y axis at (0,-3) or at -3 on the y number line. This tells us that the pink equation has a y intercept of -3. So b = -3
This only happens with the equation y = 2x-3. The other equations do not have a y intercept of -3. So this quickly rules out the other choices leaving C as the only answer.
An alternative is to find two points on the pink line, such as (0,-3) and (1,-1). Then find the slope of the line through those points. You should find the slope to be m = 2. So m = 2 and b = -3 leads to y = 2x-3. Follow similar steps for the yellow line as well.
All you have to do is plug in the tables to T. Since there's 5 tables, your new equation will be C=4x5+2. Then, you solve using pemdas.
C=4x5+2.
C=20+2
C=22
You need 22 chairs.
