Let's assume a the age of Joe
b the age of James
a=b+10 (1)
2*(a+8)=3(b+8) (2)

==> 2*(b+10+8)=3b+24
==>2b+36=3b+24
==>b=12
==>a=12+10=22
Joe is 22 years's old
James is 12 years's old.

1) Complete the sentences to explain how to multiply 4.56 x 1,000.
S_A_V [24]

Answer:

The decimal point should be moved 3 units to the right, and the result of the multiplication is 4560.

Step-by-step explanation:

Multiplication of a decimal by the nth power of 10:

In this case, the decimal point should be moved n units to the right.

Division of a decimal by the nth power of 10:

In this case, the decimal point should be moved n units to the left.

In this question:

We multiply the decimal 4.56 by 1000.

1000 is the 3rd power of 10, because 10^3 = 1000. So the decimal point should be moved 3 units to the right, and the result of the multiplication is 4560.

Solve system with substitution
SpyIntel [72]

Answer:

The cost of 1 Rose Bush= $ 8

The cost of 1 Shrub =  $12.

Step-by-step explanation:

The cost of 11 rose bushes and 4 shrubs =  $136

The cost of 2 rose bushes and 11 shrubs =  $148

Let the cost of one rose bush =  $x

and the cost of one shrub  =  $ y

Now, according to the question:

11 x + 4 y = 136

and 2 x + 11 y  = 148

From (1), we get that 11x  = 136 - 4y

or, x = \frac{136 - 4y}{11}

Substitute this value of x in equation (2), we get

2 x + 11 y  = 148  \implies 2( \frac{136 - 4y}{11})  + 11y  = 148

or, ( \frac{272 - 8y}{11})  + 11y  = 148  \implies 272 - 8y + 121y = 1628

or, 113 y = 1356

or, y = 1356/113 = 12

⇒ y = 12, So x  =  \frac{136 - 4y}{11}  = \frac{136 -12(4)}{11} = \frac{136 - 48}{11}  = 8

or, x  =8 and  y = 12 is the solution of the above system.

Hence, the cost of 1 rose bush  = $x = $8

and  The cost of 1 shrub = $ y = $12.
