Answer:

Step-by-step explanation:

Yes, her estimate is not good because one hat is $14.50 and 2 binders are$3.20*2=^$6.40. Those two items combined is over $20. The pencils will put the total further over $20.

Pencils are $0.30 each. So 10 pencils will cost $3.

$5 - $3 = $2

The remaining $2 is enough for 6 more pencils.

So she could buy 10+6 = 16 pencils with $5.

Step-by-step explanation:

cost for 3 pencils, a hat, and 2 binders

nasty-shy [4]

Answer:

$150.00

Step-by-step explanation:

Tenía $ 5.00

Mi mamá me dio $ 10.00 mientras que mi papá me dio $ 30.00.

Esto significa que luego tengo:

5 + 10 + 30 = $ 45.00

 

Mi tía y mi tío me dieron 100.00.

Entonces tuve:

45 + 100 = $ 145.00

Tenía otros $ 5.00.

Esto significa que en conjunto tuve:

145 + 5 = $ 150.00

Can some help ...:.....0
frozen [14]

Answer:

-4

Step-by-step explanation:

Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.

So to solve for x, set 28 and 10x+68 equal to each other.

28=10x+68

First, subtract 68 from both sides

-40=10x

Then, divide both sides by 10

-4=x

If you want to check your answer plug -4 back into the original equation.

28=10(-4)+68

28=-40+68

28=28, which is true, therefore -4 is correct.
