Rick bought 3 apples and 2 oranges for a cost of $1.55. Kim bought 4 apples and 3
3
oranges for a cost of $2.15. Find the cost of one apple.

Answers

Answer 1
Apples cost $0.35 each

Apples = x
Oranges = y

3x + 2y = 1.55
4x + 3y = 2.15

I like the substitution method
2y = -3x + 1.55
y = -1.5x + 0.775

4x + 3(-1.5x + 0.775) = 2.15
4x - 4.5x + 2.325 = 2.15
-0.5x + 2.325 = 2.15
-0.5x = -0.175
x = 0.35

Which ordered pair is a solution to the system of linear equation? 2x+ 3y=6
-3x+5y=10

Answers

Answer:

x = (-2)y = 2

Step-by-step explanation:

2x + 3y = 6________( 1 )

-3x + 5y = 10_______( 2 )

( 1 ) × 3 ---- 6x + 9y = 18_____( 3 )

( 2 ) × 2 ---- -6x + 10y = 20_____( 4 )

[tex](4) + (3) \\ 6x + 9y + ( - 6x + 10y) = 20 - 18 \\ 6x + 9y - 6x - 10y = 2 \\ y = 2[/tex]

y = 2 ,

[tex]2x + 3y = 6 \\ 2x + 3(2) = 2 \\ 2x + 6 = 2 \\ 2x = 2 - 6 \\ 2x = - 4 \\x = \frac{ - 4}{2} \\ x = ( - 2) \\ [/tex]

m/5=3(2m+1) verbal expression

Answers

Answer:

m = -15/29

Step-by-step explanation:

1) Distribute

[tex]\frac{m}{5} =6m+3[/tex]

2) Subtract 6m from both sides of the equation

[tex]\frac{m}{5} -6m=6m+3-6m[/tex]

3) Simplify

a. Find common denominator

[tex]\frac{m}{5} +\frac{5(-6)m}{5} =6m+3-6m[/tex]

b. Combine fractions with common denominator

[tex]\frac{m+5(-6)m}{5} =6m+3-6m[/tex]

c. Multiply the numbers

[tex]\frac{m-30m}{5} =6m+3-6m[/tex]

d. Combine like terms

[tex]\frac{-29m}{5} =6m+3-6m[/tex]

e. Combine like terms

[tex]\frac{-29m}{5} =3[/tex]

4) Multiply all terms by the same value to eliminate fraction denominators

[tex]5 *\frac{-29m}{5} =5*3[/tex]

5) Cancel multiplied terms that are in the denominator

[tex]-29m=5*3[/tex]

6) Multiply the numbers

[tex]-29m=15[/tex]

7) Divide both sides of the equation by the same term

[tex]\frac{-29m}{29} =\frac{15}{-29}[/tex]

8) Simplify

a. Cancel terms that are in both the numerator and denominator

[tex]m=\frac{15}{-29}[/tex]

b. Divide the numbers

[tex]m=-\frac{15}{29}[/tex]

If he arrived 2 hours before he started, what distance did liam traveled by taxi?

Answers

The answer is ten. The formula for calculating speed is as follows:

Speed = distance × time. Knowing the distance and time units is required to calculate the speed units.

Explain about the speed?

A bicycle that travels 30 meters in two seconds, for example, is moving at a rate of 15 meters per second. The speed of an object in motion varies frequently (for example, a car may travel down a street at 50 km/h, then slow to 0 km/h, and then accelerate to 30 km/h).

The rate at which a distance changes over time is referred to as speed. It has a dimension of time and distance. As a result, the SI unit of speed is formed by combining the fundamental unit of time and the fundamental unit of distance. As a result, the SI unit of speed is the meter per second (m/s).

How many solutions does this system have?
y = 5x + 6
y – 5x = 7

A. no solutions
B. 1 solution
C. 2 solutions
D. infinitely many solutions

Answers

Answer:

No Solutions

Step-by-step explanation:

The two lines never intersect

Answer:

A

Step-by-step explanation:

y = 5x + 6 → (1)

y - 5x = 7 ( add 5x to both sides )

y = 5x + 7 → (2)

Substitute y = 5x + 7 into (1)

5x + 7 = 5x + 6 ( subtract 7 from both sides )

5x = 5x - 1 ( subtract 5x from both sides )

0 = - 1 ← is False

This is a cornet maths question. How do I solve it

Answers

Answer:

Where is the image?

Step-by-step explanation:

Tell me in comments

The equation a + b + c = 235 is true because a = c = 55° and b = 125°

How to prove that a + b + c = 235?

The angle a and 125° are on the same straight line.

So, we have:

a + 125° = 180°

Subtract 125 from both sides

a = 55°

The angle b and 125° are vertical angles

So, we have:

b = 125°

The angle a and angle a are vertical angles

So, we have:

c = a

This gives

c = 55°

Add the three angles

a + b + c = 55° + 125° + 55°

Evaluate the sum

a + b + c = 235°

Hence, it is true that a + b + c = 235°
