Answer:

Nari says, “The sum of 10 and one-third of a number is 25.” She uses the bar model to write an equation to represent her statement.

A bar diagram. The top box contains 25. The bottom boxes contain 10 and one-third n.

Which equation can Nari write using the bar model?

25 = 10 + one-third n

10 = one-third n + 25

25 = 10 minus one-third

10 = one-third n minus 25

Answer:

25=10+\frac{1}{3}n.

Step-by-step explanation:

It is given that the sum of 10 and one-third of a number  is 25.

Let as consider n be the unknown number.

One-third of a number =\frac{1}{3}n

Sum of 10 and one-third of a number =10+\frac{1}{3}n

The sum of 10 and one-third of a number  is 25. It can be written as

25=10+\frac{1}{3}n

Therefore, the required equation is 25=10+\frac{1}{3}n.

Help Please.. 1 /2x + y = 4 What is the x-intercept? What is the y-intercept?
IgorC [24]

Answer:

x - intercept = 8

y - intercept = 4

Step-by-step explanation:

In order to to find x- intercept, plug y = 0, in the given equation of line.

\frac{1} {2} x+y = 4\\\\\frac{1} {2} x+0 = 4..(plug \: y = 0)\\\frac{1} {2} x = 4\\x = 2\times 4\\x = 8\\\huge \red {\boxed {\therefore x-intercept = 8}}

In order to to find y- intercept, plug x = 0, in the given equation of line.

\frac{1} {2} x+y = 4\\\\\frac{1} {2} \times 0+y = 4..(plug \: x = 0)\\0+y = 4\\y = 4\\\huge \purple {\boxed {\therefore y-intercept = 4}}

Toni can carry up to 18 Ib in her backpack. Her lunch weighs 1 1b,her gym clothes weigh 2 1b, and her books (b) weigh 31b each.H
Goshia [24]

Answer:

5 books.

Step-by-step explanation:

She can carry 18 pounds in total. She already has her lunch and her gym clothes inside her bag, which take up 1 + 2 = 3 pounds. Since 3 pounds are taken, that leaves 18 - 3 = 15 pounds for her books. Each book is 3 pounds, so she can carry 15/3 = 5 books in her backpack.
