Answer:

1/10+1/2=1/10+5/10=3/5

Step-by-step explanation:

so first you need to make 1/2 have a denominator of 10 so we multiply top and bottom by 5 which gives us 5/10. Then put that in on the right side because it is equal to the left side. Finally add 1/10+5/10= 6/10 which simplifies to 3/5

hope this helps! have a great day!

A line passes through the points(8,2) and (10,3) What is its equation in slope intercept form
LiRa [457]

Answer: y =  ½x - 2

Step-by-step explanation:

<u>Slope-intercept form: y = mx + b</u>

  • m = slope = \frac{y_{2} -y_{1} }{x_{2} -x_{1}} =\frac{3-2}{10-8} =\frac{1}{2}
  • b = y-intercept ⇒ Substitute in a given point to the function to find b

y =  ½x + b

2 =  ½(8) + b

2 = 8/2 + b

2 = 4 + b

2 - 4 = b

b = -2

<u>y =  ½x - 2</u>

VLD [36.1K]
1. You have that Karen made 40 cakes and she gives 1/5 to Andrew and 10% to Chris, then you have:

 40 cakes=5/5=1
 1/5 to Andrew⇒40x1/5=8
 10% to Chris=40x0.10=4

 1/5----8 
    x----4 

 x=4(1/5)/8
 x=1/10

 2. The fraction of the 40 cakes that she have left is:

 1-1/5-1/10

Mrs. Zamir wants to buy 8 protractors and some erasers for her classroom.She has $30.00. If protractors cost $2.65 each, how muc
goblinko [34]

Mrs. Zamir has \fbox{\bf\$8.8} left to buy eraser.

Further explanation :

Multiplication is a mathematical operation such that two real numbers are performed in such a way that they derive a third number called product.

For example:

There are two numbers 4{\text{ and 5}} then multiply both the numbers as,

4\times5=20

Therefore, 20 is the product of 4 and 5.

It is given that Mrs. Zamir wants to buy 8 protractors and some erasers for her classroom.

She has total \$30.

If the price of the protractor is \$2.65 each.

Therefore, she spends total amount of money  on protractor can be calculated by multiplying 8 protractors by 2.65 as,

\begin{aligned}n&=8\times2.65\\&=21.2\\\end{aligned}

Thus, she spends \$21.2 on protractors.

Now, she has total \$30 and \$21.2 she spends on protractors.

Therefore, she left with the amount r as,

\begin{aligned}r&=30-21.2\\&=8.8\\\end{aligned}

Therefore, she has \fbox{\bf\$8.8} amount left for eraser.
