1) 120° 2) 98° 3) 104° 4) 140°
Step-by-step explanation:
1) add the two angles together then set them equal to 180 then solve for x. Once x is found plug it in for ∠A
2) set the two angles equal to each other then solve for x. once x is found plug it in for ∠B
3) set the two angles equal to each other to find x. once x is found plug it in for ∠C
4) add the two angles together then set it equal to 180. solve for x. once x is fould plug it in for ∠D

Divide both sides by -2
-2x<10
-2 -2
x<-5
Note:when dividing with a negative the signs changes
Answer:
Step-by-step explanation:
- 2x + 7 > 17
- 2x > 17 - 7
- 2x > 10

Determine the coordinates of the point shown
•(1.5 , - 2.5)
•(-2.5 , - 1.5)
•(-5, 3)
•(-2, 1)
Answer:
There the coordinates of the point are:
(x, y) = (-2.5, 1.5)
Therefore, option 'b' is true.
Step-by-step explanation:
From the coordinate plane, it is clear that the point is located in the 2nd quadrant.
We know that the second quadrant has negative x values and positive y values.
2nd quadrant → (-, +)
The point is clearly located at the location at x=-2.5 and y=1.5
There the coordinates of the point are:
(x, y) = (-2.5, 1.5)
Therefore, option 'b' is true.

Find the measure of the missing angles.
Answer:
153* for both
Step-by-step explanation:
This makes a circle, which is 360*. One angle is given, and it is 27*. If the angle on the opposite side is the same, the total degrees so far would be 54.
Say b and c were equal. Then, the remaining 306* would be split even among them. 306/2 is 153.
Therefore, 153* is the correct answer.
Hope I helped!!!

A pizza dlivery car can travel 11 km for every gallon of gasoline it uses. If the driver's average speed is 28 km/h, how many hours can the driver travel before emptying a full 35 gallon gas tank?
Answer:
13.75 hours
Step-by-step explanation:
First, find how many km the driver can travel:
11(35)
= 385
Then, divide this by 28 to find how many hours the driver can travel:
385/28
= 13.75
So, the driver can travel 13.75 hours

Calcula el numero de vueltas ,por minuto que, da la polea pequeña mienta la grande da 40 vueltas . Sabiendo que cada polea gira de manera que el radio y el numero de vueltas son inversamente proporcionales
Esta pregunta esta incompleta
Pregunta completa
Calcula el número de vueltas por minuto que hace la polea pequeña mientras que la grande hace 40 vueltas. Sabiendo que cada polea gira de manera que el radio y el número de vueltas son inversamente proporcionales.
El radio de la polea pequeña = 3 cm.
El radio de la polea grande = 9 cm
Answer:
120 vueltas por minuto
Step-by-step explanation:
El radio y el número de vueltas son inversamente proporcionales.
Por lo tanto
R = Radio
T = El número de vueltas por minuto
R ∝ 1 / T
R = k / T
Donde k es constante de proporcionalidad
Polea grande
R = 9 cm
T = 40 vueltas
9 = k / 40
k = 9 × 40
k = 360
Debemos encontrar el número de vueltas para la polea pequeña, por lo tanto,
R = k / T
k = 360, R = 3 cm
3 = 360 / T
3 × T = 360
T = 360/3
T = 120 vueltas
El número de vueltas de la polea pequeña = 120 vueltas por minuto
IM IN NEED OF HELP .!!Antonio is at Best Buy and all TV's are 30% off. He finds a 75" OLED that he
wants, the price is $1500. What is the discount amount and how much did he
pay for the TV? Write and equation
Answer:
$450. The amount Antonio bought the tv for was $450.
Step-by-step explanation:
If all the tv's are 30%, multiple 30 by the price of the tv he wants, giving you 45000. Then, divide by 100 because a percent is out of a hundred, giving you $450

A tree initially measured 18 feet tall. Over the next 312 years, it grew to a final height of 3512 feet. During those 312 years, what was the average yearly growth rate of the height of the tree?
Answer:
Average growth= 11.20 feet
Step-by-step explanation:
First, we need to calculate the total growth during those 312 years:
Total growth= 3,512 - 18
Total growth= 3,494 feet
Now, the average growth:
Average growth= total growth / number of years
Average growth= 3,494 / 312
Average growth= 11.20 feet

Answer:
Option 1
Step-by-step explanation:
-4x+6y-5z=60
for x-int, solve for x when y=0, z=0
-4x+6(0)-5(0)=60
x=-15 (-15, 0,0)
for y-int, solve for y when x=0, z=0
y=10 (0, 10,0)
for z-int, solve for z when x=0, y=0
z=-12 (0, 0,-12)
