Answers

From largest to smallest:

3 hundreds (300) , 6 tens (60) , 8 ones (8)

hope this helped :)
3 hundreds>6 tens>8ones
Because:
3 hundreds=300
6 tens=60
8 ones=8
Then 300>60>8
Which is...
3 hundreds>6 tens>8 ones

Two times Antonio’s age plus three times Sarah’s age equals 34. Sarah’s age is also five times Antonio’s age. How old is Sarah?

Answers

Let Sarah's age be s and Antonio's age be a.

According to your question,

2a + 3s = 34
s = 5a

substituting the value of s in eq. 1,

2a + 3(5a) = 34

= 2a + 15 a = 34

17a = 34

thus, a = 34/17 = 2

substituting the value of a is s,

s = 5(2)
= 10

Thus, Sarah's age is 10 years and Antonio's age is 2 years.

Answer:

sarah is 10

Step-by-step explanation:

Solve the system of equations using the substitution method.

Answers

Multiply 3x +y =23 by -4

x+4y=4
-12x+(-4y)=-92

Add together

-11x = -88

x = 8

Plug x in to find y.

8 + 4y = 4

Subtract 8 from each sides

4y = -4

Divide by 4

y = -1

So the answer is x =8, y= -1

I hope that helps!
