d= dimes

n = nickels

d =n+7

n*.05+.1*d = 1.90

substitute d = n+7

.05n +.1 (n+7) = 1.9

distribute

.05n +.1n +.7 = 1.90

combine like terms

.15n +.7 = 1.9

subtract .7 from each side

.15n = 1.2

divide by .15

n=8

d=n+7

d=15

you have 8 nickels and 15 dimes

A regulation soccer field for international play is a rectangle with a length between 100 m and I 1 O m and a width between 64 1
Natalija [7]

Answer:

  • The smallest area the field could be is 6,400 m²
  • The largest area the field could be is 8,250 m²

Step-by-step explanation:

Given;

smallest possible length of the international soccer field, L₀ = 100 m

smallest possible breadth of the international soccer field, B₀ = 64 m

Largest possible length of the international soccer field, L₁ = 110 m

Largest possible breadth of the international soccer field, B₁ = 75 m

Area of a rectangle is given by;

A = L x B

The smallest area the field could be is calculated as;

A₀ = L₀ x B₀

A₀ = 100 m x 64 m

A₀ = 6,400 m²

The largest area the field could be is calculated as;

A₁ = L₁ x B₁

A₁ = 110 m x 75 m

A₁ = 8,250 m²

the monthly budget for the front of the house is $18,000. you spent 9% of the budget on fresh flowers. How much did you spend on
Kipish [7]

To find how much was spent on fresh flowers, we just multiply 9% to the monthly budget, which is $18,000.

To multiply a percent to a number, we must first turn the percent into a decimal. Just divide the percent by 100 to get the decimal form. 9% is 0.09.

0.09 \times 18000 = 1620

$1620 was spent on fresh flowers (that's quite a lot of money!)
