Answer:
y=1, x=2
Step-by-step explanation:
x+y=3
x-y=1
Using elimination method
x-x+y--y=3-1
2y= 2
y=1
Substitute y=1 into equation 2
x-1=1
x=1+1
x=2
Answer:
x=1!y=2 submitted that values in question u got answers see please likable
What is the answer to this ?
Answer:
x - 1 and 5x - 7
Step-by-step explanation:
f(x) + g(x)
= 3x - 4 - 2x + 3 ← collect like terms
= x - 1
f(x) - g(x)
= 3x - 4 - (- 2x + 3) ← distribute parenthesis by - 1
= 3x - 4 + 2x - 3 ← collect like terms
= 5x - 7

If frank have 395 marbles he putting in putting 22 in each bag how many marbles will he have in the bags that is not full
Answer:
21 bags are not full.
Step-by-step explanation:
Given that,
Total no. of marbles = 395
He is putting 22 marbles in each bags.
We need to find the number of marbles will he have in the bags that is not full. It can be calculated by dividing total no. of marbles and the no. of marbles in each bags.
[tex]x=\dfrac{395}{22}\\\\=17.95\\\\\text{or}\\\\=17\dfrac{21}{22}[/tex]
So, it means 17 bags are full but 21 bags are not full.
Can anybody answer this??
Answer:
(x, y) represent coordinates, m represents slope, and b represents the y-intercept

Answer:
a. x = 5, AB = 14, BC = 8
Step-by-step explanation:
✔️Both triangles are similar, therefore their side lengths are proportional to each other.
Thus:
[tex] \frac{2x + 4}{x + 3} = \frac{7}{4} [/tex]
Cross multiply
[tex] 4(2x + 4) = 7(x + 3) [/tex]
[tex] 8x + 16= 7x + 21 [/tex]
Collect like terms
[tex] 8x - 7x = -16 + 21 [/tex]
[tex] x = 5 [/tex]
✔️AB = 2x + 4
Plug in the value of x
AB = 2(5) + 4
AB = 14
✔️BC = x + 3
Plug in the value of x
BC = 5 + 3
BC = 8

There are 24 cars in the pool and 16 vans totally 40 total vehicles
If were to pick a random vehicle from the pool the odds of it being a car is equal to
number of cars in the pool/number of vehicles in the pool
This means the odds of you randomly picking a car is 24/40 which simplifes
to 3/5

Write in slope-intercept form an equation of the line that passes through the points (−4, 2) and (6,−3).
Answer:
y = -0.5xStep-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(−4, 2) ⇒ x₁ = −4, y₁ = 2
(6,−3) ⇒ x₂ = 6, y₂ = −3
So the slope:
[tex]\bold{m=\dfrac{-3-2}{6+4}=\dfrac{-5}{10}=-0.5}[/tex]
The point-slope form of the equation of the line passing through point (x₀,y₀) and with slope m is: y - y₀ = m(x - x₀)
m = -0.5
(−4, 2) ⇒ x₀ = −4, y₀ = 2
Therefore:
y - 2 = -0.5(x - (-4))
y - 2 = -0.5x - 2 {add 2 to both sides}
y = -0.5x ← the slope-intercept form of the equation (b=0)

Find the common difference for the following sequence and fill in the missing terms. Show all calculations. 2, 13, 24, 35, __, __
Step-by-step explanation:
Hey there!
Given sequences are; 2 , 13 , 24 , 35 , _ , _ .
Now,
Common difference (d) = 2nd term - 1st term. = 13-2 = 11
When we subtract 1st term from 2nd term we find 11 and when we subtract 2nd term from 3rd term we get 11. This means our common difference is 11.
Now, let's find the nrh term of the sequence.
nth term= a1 + (n-1)d ( a1= 1st term, d= common difference)
nth = 2+ (n-1) 11
= 2 + 11n - 11
= 11n - 9
Let's check if we have got nth term correct.
a1= 1*11 - 9 = 2
a2 = 2*11-9 = 13
a3 = 3*11 - 9 = 24
a4 = 4*11-9 = 35
So, we got our nth term.
Let's find remaining sequence.
a5= 5*11 - 9 = 46.
a6= 6*11 - 9 = 57.
Therefore, the remaining terms are : 46 and 57.
Hope it helps...
2+11=13
13+11=24
24+11=35
35+11=46
46+11=47

Find the coordinates of triangle ABC A(2,1) B(3,0) C(1,-2) after a dilation with a scale factor of 3
Answer:
Remember the key word”factor” which means to multiply. Multiple all those numbers by 3!
Step-by-step explanation:I’m going to do 2 of them and you can do the last one (2,1)x3= the dilation (6,3). (3,0)x 3 gives the dilation (9,0). (1,-2)x3 gives the dilation of (3,-6). See it’s very easy.
The speed of light is about 300,000 kilometers per second. The Sun is about 93 million miles from Earth. How many minutes does it take for the sunlight to reach Earth? Round to the nearest tenth if necessary.
Answer: 8.3 minutes
Step-by-step explanation:
1 mile is to 1.60934km so 93 million miles is:
= 93 * 1.609
= 149,637,000 km
Travelling at 300,000 km per second, the number of seconds it takes is:
= 149,637,000/300,000
= 498.79 secs
In minutes this is:
= 498.79/60
= 8.3 minutes
a piece of wood is cut in the ratio 3:7 if the shorter piece is 45 cm long,how long is the whole piece of wood?
Answer:
150 cm
Step-by-step explanation:
45/3 * 10 = 15 * 10 =150
check: 150 * 0.3 = 45
150 * 0.7 = 105
105+45 = 150
Please help me I just can’t figure this out. I’ll mark you brainiest if you know it but ONLY if you know it
Answer:
Step-by-step explanation:
All square angles are 90° exactly 90° so we can use that to your advantage. since "7x + 3" is one of the square's angles, that means 7x + 3 must equal 90°. (7x + 3)° = 90°.
7x + 3 = 90
7x = 90 - 3
7x = 87
7x/7 = 87/7
x = 87/7
Determine the value of x in the diagram.
