The system of equations that represents Candace's and Amar's combined money is c + a = 85.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Given, Candace has $15 more than Amar.

Assuming Amar has $a.

∴  Candace(c) has $(x + 15).

Their combined money totals $85.

So, the equation that represents their combined money is

x + (x + 15) = 85 or a + c = 85.

Answer:

D. 11

Step-by-step explanation:

Add all the numbers and divide by 4

Answer:

The first plant manufactures 2x + 21 more items daily.

Step-by-step explanation:

Given that:

Production level of plant one = 7x + 19

Production level of plant two = 5x -2

To find the number of items first plant manufactures more than second plant, we will find the difference between production levels.

Difference = (7x + 19) - (5x - 2)

Difference = 7x + 19 - 5x + 2

Difference = 2x + 21

Hence,

The first plant manufactures 2x + 21 more items daily.

Answer:

I. Volume = 301.6 cm³ (to 1d.p)

II. CSA = 188.5 cm² (to 1d.p)

Step-by-step explanation:

Given the following data;

Height, h = 8cm

Radius, r = 6cm

Curved length = 10cm

a. To find the volume of the cone

[tex] V = \frac{1}{3} \pi r^{2}h[/tex]

Where;

Substituting into the equation, we have;

[tex] Volume = \frac{1}{3} * 3.142*6^{2}*8 [/tex]

[tex] Volume = \frac{1}{3} * 3.142*36*8 [/tex]

[tex] Volume = 3.142*12*8 [/tex]

Volume = 301.6 cm³ (to 1d.p)

b. The curved surface area of the cone

[tex] CSA = \pi rl[/tex]

Where;

Substituting into the equation, we have;

[tex] CSA = 3.142*6*10 [/tex]

CSA = 188.5 cm² (to 1d.p)

Step-by-step explanation:

2 is 2/3 of 3

60 is 2/3 of 90

so on...

Answer:

2/3

Step-by-step explanation:

So find the change in x first....1 + 2 = 3....so, change in x is +2

Next find the change in y....-4 + 3 = -1....so, change in y is +3

Slope equals change in y/ change in x

So, the slope is 2/3

Answer:

B.) 9 in.

Step-by-step explanation:

a^2 + b^2 = c^2

a^2 + 12^2 = 15^2

a^2 + 144 = 225

a^2 = 225 - 144

a^2 = 81

√a^2 = √81

a = 9

Answer:

The answer is C.

Step-by-step explanation:

I did the test and got it right. :)

The correct is C = Multiply the first equation by 2 and the second equation by 3.

The elimination method exists utilized to solve a system of linear equations. It is the most widely used and simple method as it concerns fewer calculations and steps. In this manner, we eliminate one of the two variables and test to solve equations with one variable.

if we'll multiply the first equation by 2 and second by 3 we will be able to solve the equation by elimination.

(-3x+2y=16) X 2 = -6x + 4y = 32

(2x+5y=21) X 3 = 6x + 15y = 63

the coeffients of x gets cancelled out on adding the new equations

4y+ 15y = 32+ 63

19y = 95

y= 95/19
