Answer:
[tex](1)\ -\frac{6}{5}[/tex]
Equivalents: -12/10, -18/15, -24/20, - 30/25, -36/30
[tex](2)\ -\frac{8}{10}[/tex]
Equivalents: -4/5, 16/20, -24/30, -32/40, -80/100
Step-by-step explanation:
Given
[tex](1)\ -\frac{6}{5}[/tex]
[tex](2)\ -\frac{8}{10}[/tex]
Required
5 equivalent numbers for each
To do this, we carry out the same operation on the numerator and the denominator of the fraction
[tex](1)\ -\frac{6}{5}[/tex]
Multiply by 2/2
[tex]-\frac{6}{5} * \frac{2}{2} = -\frac{12}{10}[/tex]
by 3/3
[tex]-\frac{6}{5} * \frac{3}{3} = -\frac{18}{15}[/tex]
by 4/4
[tex]-\frac{6}{5} * \frac{4}{4} = -\frac{24}{20}[/tex]
by 5/5
[tex]-\frac{6}{5} * \frac{5}{5} = -\frac{30}{25}[/tex]
by 6/6
[tex]-\frac{6}{5} * \frac{6}{6} = -\frac{36}{30}[/tex]
[tex](2)\ -\frac{8}{10}[/tex]
Divide by 2/2
[tex]-\frac{8}{10}= -\frac{8/2}{10/2}[/tex]
[tex]-\frac{8}{10}= -\frac{4}{5}[/tex]
Multiply by 2/2
[tex]-\frac{8}{10} =-\frac{8*2}{10*2}[/tex]
[tex]-\frac{8}{10}= -\frac{16}{20}[/tex]
Multiply by 3/3
[tex]-\frac{8}{10}= -\frac{8*3}{10*3}[/tex]
[tex]-\frac{8}{10} =-\frac{24}{30}[/tex]
Multiply by 4/4
[tex]-\frac{8}{10} = -\frac{8*4}{10*4}[/tex]
[tex]-\frac{8}{10}= -\frac{32}{40}[/tex]
Multiply by 10/10
[tex]-\frac{8}{10}= -\frac{8}{10} * \frac{10}{10}[/tex]
[tex]-\frac{8}{10}= -\frac{80}{100}[/tex]

Answer:
12 games
Step-by-step explanation:
Let x be the number of games played
The y won 75% of the games played and that was 9
x * 75% = 9
Change to decimal form
x * .75 = 9
Divide each side by .75
x * .75 /.75 = 9/.75
x =12
They played 12 games
Answer:
Step-by-step explanation:
75g/100=9
g=900/75
g=12

fencing for $25.50/m. Her family has $165 to spend. What dimensions should Sarah use to build a
garden with the greatest area? Round all answers to 2 decimal places.
Answer:
circle with circumference of 6.47m
Step-by-step explanation:
1. $165/$25.50=6.47058823529m
2. she should use a circle because they have the greatest area, the circle should have a circumference of 6.47m.

Step-by-step explanation:
Gia receives an allowance of $2 a week and already has $20 in savings. Michael receives an allowance of $3 a week and already has $5 in savings. Gia and Michael both save their entire allowance. After how many weeks, will Gia and Michael have the same amount in savings? How much money will they have?
Answer:
After 15 weeks, Gia and Micheal will both have $50 in savings.
Step-by-step explanation:
For Gia:
We start at $20 since she already has $20 in savings, we will add that to how much Gia will receive in 15 weeks.
Gia receives $2 a week and therefore in 15 weeks she will have $50.
= 2x15 = $30
= 30+20 = $50
For Micheal:
We start at $5 since he already has $5 in savings, we will add that to how much Micheal will receive in 15 weeks.
Micheal receives $3 a week and therefore in 15 weeks he will receive $50
= 3x15 = $45
= 5+45 = $50

(a) Find 6% of 350 (b) Find 25% 80 (c) Find 15% of 35.00
% is read as percent, and cent means 100.
In this case 6% is 6 out of 100 or 6/100.
so 6%*350=350*6/100=21
The second case its 25%*80=25/100*80=20
The third case, its 35*15/100=5.25

Enter the number that
goes beneath the
radical symbol.
(-1,-3)
Answer:
50
Step-by-step explanation:
[tex]\boxed{distance \: between \: 2 \: points = \sqrt{(y1 - y2)^{2} + (x1 - x2) {}^{2} }}[/tex]
Distance between the 2 points
[tex] = \sqrt{( - 3 - 2) {}^{2} +( - 1 - 4) {}^{2} } [/tex]
[tex] = \sqrt{( - 5)^{2} + ( - 5)^{2} } [/tex]
[tex] = \sqrt{25 + 25} [/tex]
[tex] = \sqrt{50} [/tex]
Thus, the number that goes beneath the radical symbol is 50.

Your friend spends 3+4x minutes lifting weights and 9x+5 running a treadmill. Write a polynomial that represents how much time is spent on running on the treadmill than lifting weights. Answer quick!!!
Answer:
[tex]Polynomial = 5x+ 2[/tex]
Step-by-step explanation:
Given
[tex]Weights = 3 + 4x[/tex]
[tex]Treadmill = 9x + 5[/tex]
Required
Polynomial that represents time spent running treadmill than weight lifting
To do this, we simply subtract weights from treadmill
i.e.
[tex]Polynomial = Treadmill - Weights[/tex]
[tex]Polynomial = 9x + 5 - (3 + 4x)[/tex]
[tex]Polynomial = 9x + 5 - 3 - 4x[/tex]
[tex]Polynomial = 9x - 4x+ 5 - 3[/tex]
[tex]Polynomial = 5x+ 2[/tex]

X+3y=-2

USE SYSTEMS BY SUBSTITUTION.
X=
Y=
Answer:
X=-2
Y=0
Step-by-step explanation:
X+y=-2 = x=-2-y
3x+4y=-6
3(-2-y)+4y=-6
-6-3y+4y=-6
y=0
x+3(0)=-2
x=-2
Answer:
[tex]\boxed {\boxed {\sf (-2,0)}}[/tex]
Step-by-step explanation:
To solve by substitution we must first isolate 1 variable in an equation.
Let's use the first equation.
[tex]x+3y= -2[/tex]
Subtract 3y from both sides to isolate the variable x.
[tex]x+3y-3y= -2 -3y[/tex]
[tex]x= -2 -3y[/tex]
Now we can substitute the expression (-2-3y) in for x in the second equation.
[tex]3x+4y= -6[/tex]
[tex]3(-2-3y)+4y= -6[/tex]
Distribute the 3. Multiply each term inside the parentheses by 3.
[tex](3*-2)+ (3*-3y)+4y=-6\\-6-9y+4y=-6[/tex]
Combine the like terms on the left side.
[tex]-6-5y= -6[/tex]
Add 6 to both sides to isolate the variable.
[tex]-6+6-5y=-6+6\\-5y=0[/tex]
Divide both sides by -5.
[tex]-5y/-5=0/-5 \\y=0[/tex]
Now we know that y is equal to 0 and can substitute it into the first equation and find x.
[tex]x+3(0)=-2[/tex]
[tex]x+0=-2 \\x= -2[/tex]
x is equal to -2 and y is equal to 0.
