Add the areas of all the sides of the shape.
A triangle's area: 1/2bh
The two triangles' area=24*9=216
The bottom side: 40*24=960
The two other sides: 30*40=1200
Add everything: 216+960+1200=2376

Step-by-step explanation:
Part A:
C = 10t + s
Part B:
10(3) + 8
30 + 8 = $38
Um this seems really confusing!
Answer:
(-3 , 0)
Step-by-step explanation:
The x-intercept is the point on which lies on the x-axis, so when the y is equal to 0.
They y-value can be seen as gaining 16 whole numbers every time the x gains 3.
1. Add intervals of +16 to the y-value (from -32) and intervals of +3 to the x-value (from -9) until the y-value equals 0.
Show:
(-9+3 , -32+16) = (-6 , -16)
(-6+3 , -16+16) = (-3 , 0)
The y-value in the end, is 0 with a x-value of -3.
Answer:
Step-by-step explanation:
Biking is x and bussing is y. We know that the total distance is 325. Thus, the first equation in this system is
x + y = 325 (which says that the km traveled by bike plus the km traveled by bus totaled 325 km).
We also know that the pair biked 75 km more than they rode, giving us the second equation in our system:
x = y + 75. Now we use simple substitution and plug y + 75 in for x in the first equation:
(y + 75) + y = 325 and
2y + 75 = 325 and
2y = 250 so
y = 125 km. They rode the bus for 125 km and biked for 325 - 125 which is 200. And the difference is 75 km, as it should be!
