Simplify 4y — 4ys + 2y – 5у — 54 – 34

Mathematics
1 answer:
Oxana [17]3 years ago
4 0

Answer:

-4ys + y - 88

Step-by-step explanation:

When we have to simplify equations that have different variables, we always have to look at the like terms, which the like terms are ones that contain the same value and variable. So let's look at our equation :

4y — 4ys + 2y – 5у — 54 – 34

We can see three different terms here :

ys, y, and a constant term.

The rule is that we can only combine two properties that have the same like term, so in the equation :

4y — 4ys + 2y – 5у — 54 – 34

These have the same variable, therefore we can combine like terms.

4y + 2y - 5y

6y - 5y

y

Now implace it into the equation :

y — 4ys — 54 – 34

Onto the next property :

y — 4ys — 54 – 34

This is alone, therefore we can leave it :

y — 4ys — 54 – 34

These two are the same property, so do the following :

-54 - 34

-88

Impace into the equation :

y - 4ys - 88

Now that we have no same common like terms, we can order our equation to greatest value to least :

-4ys + y - 88

Two mechanics worked on a car. The first mechanic worked for
Temka [501]
Write a system of equations:

x + y = 125

20x + 15y = 2100

Solving:

x = 125 - y

20(125 - y) + 15y = 2100
2500 - 20y + 15y = 2100
2500 - 5y = 2100
-5y = 2100 - 2500
-5y = -400
y=80

x + 80 = 125
x = 125 - 80
x = 45

The first charges 45$ per hour and the second charges 80$ per hour

A man purchased a car selling for RM12,750 by making instalment payments. If he was charged 4% based on the reducing balance and
a_sh-v [17]

Answer:

48 months

Step-by-step explanation:

Cost of car = RM12,750

interest charged = 4% = 0.04

total interest paid = RM1,041.25

Now,

Using the Constant Ratio formula

r = \frac{24\times\textup{i}}{\textup{P(n+1)}}

here,

i is the interest paid

P is the principle

n is the number of monthly installments

r is the interest rate

on substituting the respective values, we get

0.04 = \frac{24\times\textup{1041.25}}{\textup{12,750(n+1)}}

or

n + 1 = 49

or

n = 48 months
