4 boys weighed themselves in different pairs and alone. The weights of the pairs were 110kg, 112 kg, 113kg, 118kg, 121 kg, and the weight of one pair was lost. The total weight of the 4 boys was 230kg. What was the lost weight?
Answer:
116
Step-by-step explanation:
you can use variables
a+b=110
a+c=112
a+d=113
b+c=118
b+d=121
add up the weights and you get 574 kg (you need to find c+d)
3a+3b+2c+2d=574
a+b+c+d = 230 as given then you multiply by 3 so you can cancel out 3a and 3b and subtract 690-574 because we multiplied by 3
you are left with c+d=116

Given the equation 100 - 20t = 12r +4P,
solve for P. Find the P values when
(r= -2, -5, and 5) and (t=4, -4, and 8).
Answer:
P = -3r -5t + 25
r(-2): P = -5t + 31
r(-5): P = −5t + 40
r(5): P = −5t + 10
t(4): P = −3r + 5
t(-4): P = −3r + 45
t(8): P = −3r − 15

Rewrite the equation y=|x+3|-1 as two linear functions f and g with restricted domains
You can write it as:
f(x) = - x - 4
{x | x ≤ -3, x ∈ R}
f(x) = x + 2
{x | x ≥ -3, x ∈ R}
if f(x)=2x^2-5 and g(x)=5x+7 g(x)=
Answer in the picture.
A function assigns the values. The value of f(g(x)) is 50x² + 140x + 93.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the value of f(x)=2x²-5 and g(x)=5x+7, therefore, the value of f(g(x)) can be written as,
f(g(x)) = 2(5x+7)²-5
f(g(x)) = 2(25x²+49+70x)-5
f(g(x)) = 50x² + 98 + 140x - 5
f(g(x)) = 50x² + 140x + 93
Hence, the value of f(g(x)) is 50x² + 140x + 93.

Write the ratio in simplest form. 10 seconds to 5 min
Answer:
10:5
Step-by-step explanation:
The simplest form of the ratio 10 seconds to 5 min will be;
⇒ 1 : 30
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
The ratio is,
⇒ 10 seconds to 5 minutes.
Now,
Since, The ratio of two numbers has always same units.
So, We change 5 minutes into seconds as;
Since, 1 minutes = 60 seconds
Hence, 5 minutes = 5 x 60 seconds
= 300 seconds
Thus, The ratio becomes,
⇒ 10 seconds to 300 seconds
⇒ 10 : 300
⇒ 10 / 300
⇒ 1 / 30
⇒ 1 : 30
Thus, The simplest form of the ratio 10 seconds to 5 min will be;
⇒ 1 : 30

7 3 If you were to graph a line with a slope of 3/2 that intercepts the y-axis at -2 on the coordinate plane, one point on that line would have a y coordinate of 4 with an x coordinate of what number?
Answer:
4
Step-by-step explanation:
Make a graph.
Start at negative 2 because that's the y intercept. Remember that a minus sign in front of the y intercept just means it's negative.
The slope is basically the rise over the run. How much you go UP divided by how much you run. Since the slope is 3/2, we go up 3 and right 2.
