How do you solve for x intercept?
Answer:
Hey there!
Triangle PQT and RQT are congruent by AAS. AAS means that one side is congruent, and two angles are congruent.
Since these triangles share one side, then the side is congruent.
PR is a straight line, so if angle Q is 90 degrees, then the supplementary angle is also 90 degrees.
Finally, the diagram shows that angles R and P are congruent to each other.
Hope this helps :)
If Tim spends a third of each weekday sleeping, this means he spends
8/24 hours a day asleep. If he spends 7/24 hours of each weekday in
school too, this means the combined time he spends sleeping and in
school is 8/24 + 7/24, so he spends 15/24 hours each weekday sleeping in
school (three more hours than half a day)
240 people didn't like any of the music type.
Step-by-step explanation:
- Step 1: Given total people who took the survey = 1000. Find the number of people who liked each type of music.
Number of people who liked pop = 30% of 1000 = 30/100 × 1000 = 300
Number of people who liked rock = 26% of 1000 = 26/100 × 1000 = 260
Number of people who liked pop = 20% of 1000 = 20/100 × 1000 = 200
- Step 2: Find the total number of people who didn't like any of the music type.
Number of people who didn't like any of the music type = 1000 - (300 + 260 + 200)
= 1000 - 760
= 240
Answer:
Her error was multiplying -3 and -4 which gives +12 but she wrote -12 instead
Step-by-step explanation:
Mariana workings:
-3(2x - 4) = -12
-6x - 12 = -12
Her error was multiplying -3 and -4 which gives +12 but she wrote -12 instead
-6x = 0
x=0
Correct workings:
-3(2x - 4) = -12
-6x + 12 = - 12
-6x = -12 - 12
-6x = -24
x = -24/-6
x = 4
