Answer:
10 : 12 is equivalent to 5 : 6 and 20 : 24.
Step-by-step explanation:
You can divide and multiply the ratio by 2 to get an equivalent ratio.
The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24 Therefore, option (C) will be correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
As per the given ratio, 10:12.
Divide numerator and denominator by 2
(10/2):(12/2) = 5:6.

Okay so my test said (using elimination (add or sub) find the solution to the following system of equations. 5x+3y=9 2x -3y=5) and I’m confused
Answer:
x = 2, y = -1/3
Step-by-step explanation:
I'm pretty sure the question is asking for the values of x and y. By finding these values you will need to use elimination.
Equations given:
5x + 3y = 9
2x - 3y = 5
To find x:
5x + 3y + 2x - 3y = 9 + 5 (add to eliminate y to solve for x)
7x = 14
x = 2
To find y:
5(2) + 3y = 9
10 + 3y = 9
3y = -1
y = -1/3
Therefore, x = 2 and y = -1/3

Answer:
DE = 37Step-by-step explanation:
AD = DC and BE=EC ⇒
DE = 1/2AB
4x + 1 = 1/2(11x - 25)2(4x + 1) = 11x - 258x + 2 = 11x - 2511x - 8x = 2 + 253x = 27x = 27/3x = 9DE = 4*9 + 1 = 36 + 1 = 37
AD = DC
BE = EC
It gives that 2(DE) = AB
To Find:The length of DE.
Explanation:According to the question,
2(DE) = AB
By putting the respected values, we get
2( 4x + 1 ) = 11x - 25
or, 8x + 2 = 11x - 25
or, 25 + 2 = 11x - 8x ( transposition method )
or, 27 = 3x
or, x = 27/3 = 9
The value of x is 9.
DE = 4(9) + 1 = 36 + 1 = 37
Answer:DE = 37

During the life of a $2500 loan, the interest paid is $318.75. If the interest rate is 8.5%, how long was the loan?
Answer:
1.5 years
Step-by-step explanation:
Simple Interest I = PRT
Principal = 2500, Rate R= 8.5%, SI = 318.75, T = ?
Now, substituting the above value
318.75 = 2500*0.085 * T
T = 318.75 / 2500*0.085 years
T = 318.75 / 2500*0.085 years
T = 318.75 / 212.5 years
T = 1.5 years

An isosceles triangle has a perimeter of 50 cm. The congruent sides
measure (2x + 3) cm. The length of the third side is 7x cm. What is the
value of x?
Answer:
4
Step-by-step explanation:
As, the measure of one congruent side is = 2x + 3
So, bc there are 2 congrent sides, =( 2x + 3) + (2x +3) = 4x + 6
Now perimeter= the length of the 2 sides + third side
Perimeter = (4x + 6) + (7x) = 50 cm
So, 11x + 6 = 50
So, 11x = 50 - 6 = 44
11x = 44
x = 44/11
x = 4cm.
Determine f(4) for the function f(x)=2/5x+11
Answer:
63/5 in improper form and 12 and 3/5 in mixed form
Step-by-step explanation:
f(x) = 2/5x + 11
Substitute in value of x for the equation
f(4) = 2/5(4) + 11
f(4) = 8/5 + 11
f(4) = 8/5 + 55/5
f(4) = 63/5 or 12 and 3/5
So, the answer should be 63/5 in improper form and 12 and 3/5 in mixed form.
Answer:
Step-by-step explanation:
f(x) = [tex]\frac{2}{5}x + 11[/tex]
f(4) = [tex]\frac{2}{5}*4 +11\\[/tex]
[tex]=\frac{8}{5}+11\\\\=\frac{8}{5}+\frac{11*5}{1*5}\\\\=\frac{8}{5} + \frac{55}{5}\\\\=\frac{63}{5}\\\\=12\frac{3}{5}[/tex]
