To solve this problem, it is easiest to set up a system of equations. Let's let the variable s represent the cost of a shirt and the variable j represent the cost of jackets. According to the given information, we can set up the following equations (because cost multiplied by quantity yields price):
3s + 4j = 360
1s + 3j = 220
Next, we can manipulate the second equation so that it equals s in terms of j. We do this by subtracting 3j from both sides of the equation, as shown below:
s = 220 - 3j
After that, we should substitute in this value for the variable s in the first equation.
3(220-3j) + 4j = 360
Next, we should use the distributive property to simplify the left side of the equation.
660 - 9j + 4j = 360
Then, we should simplify the left side of the equation by combining like terms.
660 - 5j = 360
After, we can subtract 660 from both sides of the equation to get the variable term alone.
-5j = -300
Finally, we should divide both sides of the equation by -5 in order to get the variable j alone.
j = 60
Now that we know the value of the variable j, we should substitute this value into one of the original equations and solve using division and subtraction to isolate the variable.
3s + 4j = 360
3s + 4(60) = 360
3s + 240 = 360
3s = 120
s = 40
Therefore, the cost of one shirt is $40.
Hope this helps!
First you would have to do V=bh to the power of 2
B= base
H= height
Base= 62
Height. 10
Its a triangle right? So you have to divide by 2
Now its V=2bh
V=2(62)(10)
62
x62
------
3844x10=38440 divide by 2
Then that should be your answer please tell me if im wrong i would love the suport
Btw this is all by memory Thanks!

Lines can be named using any two points on the line or using a single cusive lowercase letter.
Answer:
Step-by-step explanation:
Given that,
Initial speed of a vehicle, u = 25 km/hr = 6.95 m/s
Final speed of a vehicle, v = 1200 km/hr = 333.34 m/s
Time, t = 60 s
We need to find the acceleration of the vehicle. It is equal to the rate of change of velocity. It can be given by :
So, the acceleration of the vehicle is .
It equals 5.1962.... If it's 3/2 then you can do 3 divided by 2 and you'll get 1.5. If you have a scientific calculator you can do 3 to the power of 1.5 which will get you your answer.
