Answer:
90% is close to 75
Step-by-step explanation:
90% of a number would be 3 times 30% of a number. As a result we can assume 90% of the number would be around 3(25) or 75
Answer:
8
Step-by-step explanation:
4/13 x/26
4 times 26, the that number divided by 4. Its called the butterfly/cross multiplying method
The yellow squad coordinate is (-3,2)
Answer:
5 feet / 6 feet = 0.8333
Step-by-step explanation:
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.
