Solve for R using cross multiplication

Mathematics
1 answer:
topjm [15]3 years ago
8 0

R/ r+ 15 = 3/8

Cross multiply: top of one side multiplied by bottom of other side:

R x 8 = 3 x r+ 15

Simplify:

8r = 3r + 45

Subtract 3r from both sides:

5r = 45

Divide both sides by 5:

R = 9

Select the table that represents the function f(x) = 3x + 5
erma4kov [3.2K]

the function f(x) = 3x + 5 has a slope of 3 and a y-intercept of (0,5).


Table 1, reproduced below, shows that for every unit increase in x, y increases by 3, and that y=5 when x=0 (which is the y-intercept).


Table 1 is the correct answer.



.x y

-3 -4

-2 -1

-1 2

Please help me on this one I wrote it out :(
Stels [109]

Answer:

D) 3

Step-by-step explanation:

22 * 2 = 44

To have a remainder 3, the number should be 44 + 3 = 47

47 ÷ 22 , leaves a remainder 3.

47 +22 = 69

69 ÷ 3  leaves a remainder 3.

69 +22 = 91

91 ÷ 3 leaves a remainder 3.

Answer: 47 , 69 , 91

Please help me with this
Zarrin [17]
The two end points of our line are (0,2.5) and (5,5.5). to find our slope we need  to find our n difference (higher value - lower value) and our C difference (same as n) which would be 5 and 3. now we put our cost difference over our miles difference and get our slope (5/3). this means we still need out starting point. which is a cost of 2.5. the equation is C = (slope)5/3n + (starting value)2.5

Big ideas math 1.2 Practice A number 19

By applying Segment Addition Postulate, segment FH is equal to 24 units.

<h3>What is a point?</h3>

A point can be defined as a zero dimensional geometric object and it is generally represented by a dot.

<h3>What is a line segment?</h3>

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

<u>Given the following data:</u>

  • Line segment FG = 37.
  • Segment HG = 13.

Since point H lies on line segment FG, we would apply Segment Addition Postulate to determine segment FH as follows:

FG = HG + FH

37 = 13 + FH

FH = 37 - 13

FH = 24 units.

Complete Question:

Given that line segment FG = 37 and segment HG = 13, find segment FH.
