How do you subtract an integer from another integer without using a number line or counters

Answers

Okay, so, I think I understand your problem. Not everyone knows how to subtract the different positive and negative integers, and not everyone is great at math. I understand that, so that is why I will give you a couple of tips. First off, whenever you are subtracting a negative integer and another negative integer, the answer will always be negative. When you are subtracting two positives, depending on the number values, they will either be positive or negative. And when subtracting a positive and negative, the answers will always be positive. Other then that, you can use mental math, or write out the problems on a sheet of paper.

What is the equation of a line that passes through the point (8,1) and is perpendicular to the line whose equation is y= -2/3 x + 5? A) 2X+3Y= 15
B) Y= -2/3x + 11
C) Y= 3/2x+ 11
D) y= 3/2x - 11

I am thinking its B but am not sure. I don't wanna retake this so I wanna be 100%. Thanks!!

Answers

Answer:

The equation of this line would be y = 3/2x - 11, which is the answer D.

Step-by-step explanation:

In order to find this equation we must first find the slope of the original line. The original slope (the coefficient of x) is -2/3, which means the new slope will also be 3/2 because perpendicular lines have opposite and reciprocal slopes. Now, we can use this slope along with the point in point-slope form to find the equation of the line.

y - y1 = m(x - x1)

y - 1 = 3/2(x - 8)

y - 1 = 3/2x - 12

y = 3/2x - 11

Which is the best estimate for 25% of 60

Answers

the answer is 15 because 25% is .25 x 60
To find 25% of 60
you multiply 0.25 * 60 which is 15

So, 25% of 60 is 15

Three people are kayaking. They all started at the same point and rowed in the same direction for 20 minutes. Laura rowed 7/8 mile
Daniel rowed 1/2 mile
Annabelle rowed 1/4 mile
Part A:
Did Laura row a distance greater than, less than, or equal to the combined distance of Daniel and Annabelle?

Answers

Answer:

Greater than

Step-by-step explanation:

In order to compare the distances rowed, we need to come up with a common denominator. Our least common denominator is 8 because 2 and 4 are both divisors of 8.

Laura rowed 7/8 mile

Daniel rowed 4/8 mile ((1)/(2)* 4)

Annabelle rowed 2/8 mile ((1)/(4)*2)

Daniel and Annabelle rowed a combined 6/8 mile ((4)/(8) +(2)/(8)). 7/8 is greater than 6/8. Laura rowed a distance greater than the combined distance of Daniel and Annabelle.

In a group of 48 children there are twice as many boys than girls how many girls are there

Answers

let x be the number of girls
let 2x be the number of boys
given that There are 48 children.

x+2x=48x=48/3x=16
therefore there are 16 girls in the group...
If you take 48 divied by 3 you get 16 and 16+16 =32 guys
32+16=48
16 girls
