<span>A quarter is equivalent to 25 cents or $0.25 and a nickel is equal to 5 cents or $0.05. In the given in this item, if there are x nickels then, there are x + 7 quarters. With these and the total amount known, we can now compute for the value of x.
(x)(0.05) + (x + 7)(0.25) = 2.65
Simplifying,
0.05x + 0.25x + 1.75 = 2.65
Simplifying further,
0.3x = 0.9
The value of x from the equation is 3. Hence, there are 10 quarters.</span>
<u>1 is a rational number</u> because 1 can go into 1 when dividing. <u>Irrational numbers are mostly decimals. </u>
Let the number = x
12 + x = 3x - 32
x = 3x - 44 Subtract 12 from both sides
-2x = -44 Subtract 3x from both sides
x = 22 Divide by -2
Answer:
The radius is half of the diameter of the circle and it is measured from the center of the circle to the circumference of the circle.
Step-by-step explanation:
<u><em>Answer: x<-6 *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
subtract 5 both sides of an equation.
5-2x-5>17-5
simplify.
-2x>12
multiply by -1 both sides of an equation.
(-2x)(-1)<12(-1)
simplify.
2x<-12
divide by 2 both sides of an equation.
2x/2<-12/2
-12/2=-6
12/2=6
6*2=12
12/6=2
x<-6
Hope this helps!
Thanks!
Have a great day!
