Three times the sum of two numbers is 15. One of the numbers is 9 more than one-third of the other number.
a. How can you use a system of equations to find the two numbers?
b. What are the two numbers? Show your work.
Answer:
8, - 3
Step-by-step explanation:
one number is x, the other is y
x = 1/3y + 9
=> (1/3y + 9 + y) × 3 = 15
=> y + 27 + 3y = 15
=> 4y = 15 - 27
=> 4y = - 12
=> y = - 3
x = 1/3(- 3) + 9 = 8

Answer:
E. 18 on each van and 40 on each bus
Step-by-step explanation:
3(18) + 5(40) = 254 and 10(18) + 10(40) = 580
Given that y varies inversely with x, if y=-5 when x=-6, find x when y=-2.5.
15
Explanation:
If y varies inversely as x, the two variables can be represented in an equation in the form
y
=
k
x
where
k
is some constant.
We are given that
y
=
5
when
x
=
6
. We can plug this into the above equation to find what
k
is:
5
=
k
6
30
=
k
Based on this we can create our equation:
y
=
30
x
And then find
x
when
y
=
2
:
2
=
30
x
2
x
=
30
x
=
15

Consider the equation r + 2 = 3x – 4.
a. Solve the equation using algebra.
X=
Answer:
r/6 +2 = X
Step-by-step explanation:
We want to isolate X by itself to find its value. First transpose your -4 to the other side (note that -4 will become positive)
r + 2 +4 = 3x
r + 6 = 3x
To find the X, we get rid of the 3, so divide both sides by 3
r/3 + 6/3 = x
r/3 + 2 = x
OR
(r+6)/3 = x
Both works : )
Answer:
Step-by-step explanation:
We want to solve r + 2 = 3x – 4 for x.
This means isolating x on one side. To do this, first add 4 to both sides, obtaining r + 2 + 4 =3x, or:
r + 6 = 3x
Finally, divide both sides by 3:
r + 6
x = -------------

HELP ASAP GEOMETRY 10th
Answer:
m<FEG = 23°
m<FEH = 113°
Step-by-step explanation:
A diameter is always 180° to it's corresponding arc.
The circumference or full arc of a circle is 360°.
If EG is a diameter, Arc EG is 180°.
Given that Arc EF = 134°, and Arc EG = 180°.
Arc EF + Arc EG + Arc FG = 360°.
134° + 180° + Arc FG = 360°
314° + Arc FG = 360°
–314° –314°
Arc FG = 360° – 314° = 46°
The angle formed by the two chords that make the arc is ½ the measure of that Arc.
Meaning that m<feg which is the angle formed by arc FG is ½ 46° which means that m<feg = 23°.
Given that segment EH is tangent to point E.
The rule of a segment and a tangent is that the angle formed is also ½ the measure of the arc.
This means that m<FEH = ½(Arc FG + Arc EG)
m<FEH = ½(46° + 180°) = ½(226°) = 113°
If sin A = cos B and the measure of angle A is 1.5 times the measure of angle B, find the measure of angle A
Answer:
[tex]A = 54[/tex]
Step-by-step explanation:
Given
[tex]\sin A = \cos B[/tex]
[tex]A=1.5B[/tex]
Required
Find A
If [tex]\sin A = \cos B[/tex]
Then:
[tex]A +B = 90[/tex]
Substitute [tex]A=1.5B[/tex] in [tex]A +B = 90[/tex]
[tex]1.5B + B = 90[/tex]
[tex]2.5B = 90[/tex]
Solve for B
[tex]B = \frac{90}{2.5}[/tex]
[tex]B = 36[/tex]
Substitute [tex]B = 36[/tex] in [tex]A=1.5B[/tex]
[tex]A = 1.5 * 36[/tex]
[tex]A = 54[/tex]

A garden center has 150 fruit trees to sell.
1/10 of the trees are lemon trees.
2/5 of the trees are orange trees.
1/3 of the trees are peach trees.
The rest are pear trees.
How many trees are pear trees?
Step-by-step explanation:
Take pear trees be X
1/10+2/5+1/3+x=150 (Take LCM of 10,5,3=30)
3/30+12/30+10/30+30x/30= 150
25/30+30x/30=150
25+x=150/30
X=5-25=-20 are pear trees
