Answer:
It will take 28 minutes to complete a 7-kilometer race
Step-by-step explanation:
If you can job 3 kilometers in 12 minutes, that means you can jog 1 kilometer in 4 minutes. so if you multiply 7 times 4, you would get 28. So your answer is 28 minutes.

A) (-3,-2)
B) (3,14)
C) (1,-3)
D) (1,6)
Answer:
c) (1,-3)
Step-by-step explanation:
-3<3(1)+1
-3<3+1
-3<4
4x+3y=2
2x+y=6
substitution
Answer:
(8,-10)
Step-by-step explanation:
4x+3y=2
2x+y=6--->y=-2x+6
4x+3(-2x+6)=2
4x-6x+18=2
-2x=-16
x=8
4(8)+3y=2
32+3y=2
3y=-30
y=-10
Answer:
x=8 y=-26/3
Step-by-step explanation:
2x+y=6
2x=6-y
2x-6=-y
-2x+6=y
4x+3(-2x+6)=2
4x-6x+18=2
4x-6x+16=0
-2x+16=0
-2(x-8)=0
x-8=0
x=8
4(8)+3y=6
32+3y=6
26+3y=0
3y=-26
y=-26/3

can someone help me solve these two problems? i need to find what x is.
Answer:
1. x=2
2. x= 0.33
Step-by-step explanation:
1.So to start off you have a coefficient for 2 so you have to find what 2 to the power of 2 is =4 so then you have your new problem 4x+5=13 next you need to get 4x by itself so
-5 -5
then you have 4x=8. you divide by 4 on both sides
4. 4
so then you get x=2
2.So same here find what 3 to the power of 2 is =9
New equation 4x-1=9x+4x-4. Then combine like terms on the right you cant do it on the left because that is a separate part and those dont merge like terms so
9x+4x = 13x
new equation. 4x-1=13x-4
next subtract 4x on both sides
13x-4x=9x
new equation. -1=9x-4
next add 4 to both sides
-1+4= 3
new equation. 3=9x
so then divide 9 on both sides
3÷9= 0.33
x= 0.33

In the diagram, each shape has a value and the sums of the shapes in each of the first three rows is given. Find the sum of the shapes in the fourth row.
Answer:
26
Step-by-step explanation:
2 squares + 3 circles = 31. So, the sum of the squares is divisible by two, and the sum of the circles is divisible by 3. Then, I used trial and error to figure out that the square's value is five, and the circle's value is seven. 5 + 7 + 7 = 19. 27 - 19 = 8. The triangle's value is eight. 5 + 7 + 12 = 24. It works. 15 + 7 + 4 = 26

what does x equal 7(2x+5)=4x -9 -x
PLEASEEEE HELPPPP ME
Answer: x=-4
Step-by-step explanation:
Given
7(2x+5)=4x-9-x
Expand parenthesis
14x+35=4x-9-x
Combine like terms
14x+35=3x-9
Subtract 35 on both sides
14x+35-35=3x-9-35
14x=3x-44
Subtract 3x on both sides
14x-3x=3x-44-3x
11x=-44
Divide 11 on both sides
11x/11=-44/11
x=-4

In ΔFGH, f = 60 cm, g = 10 cm and h=62 cm. Find the measure of ∠F to the nearest degree.
Answer:
74
Step-by-step explanation:
The measure of ∠F of the triangle FGH, where all the sides are known is 74 degrees to the nearest degree.
What is the law of cosine?When the three sides of a triangle is known, then to find any angle, the law of cosine is used.
It can be given as,
[tex]c^2=a^2+b^2-2ab\cos C\\a^2=c^2+b^2-2ab\cos A\\b^2=a^2+c^2-2ab\cos B[/tex]
Here, a,b and c are the sides of the triangle and A,B and C are the angles of the triangle.
In the triangle FGH the measure of the line segment f is 60 centimeter, the measure of the line segment g is 10 cm and the measure of the line segment h is 62 centimeters.
The measure of the angle ∠F has to be find out. To find the value of angle F where side f is 60 cm. Thus, put the values of the all the sides in the above formula as,
[tex]60^2=10^2+62^2-2(10)(62)\cos (F)\\3600=100+3844-1240\cos (F)\\ F=\cos^{-1}(0.27742)\\F\cong74^o[/tex]
Hence, the measure of ∠F of the triangle FGH, where all the sides are known is 74 degrees to the nearest degree.
