You haven't posted the answer choices, but Trey got the wrong answer.

The denominators must be the same in order to add the fractions. In this case, the denominators 15 and 10 are different. We cannot add in this current state.

Adding the denominators is a common mistake which you should practice to avoid.

Answer:

9/10

Step-by-step explanation:

1215+110

and solve

(12×10)+(1×15)15×10

=120+15150

=135150

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(135,150) = 15

135÷15150÷15=910

Therefore:

1215+110=910

goldenfox [79]

Answer:

A) y = x - 3/4

Step-by-step explanation:

The equation of the line with slope m and intercept b is

y = mx + b

Here were have slope = m = 1.

y-intercept = b = -3/4

Equation:

y = mx + b

y = 1x + (-3/4)

y = x - 3/4

Kate currently has an account balance of $7,194.66. She opened the account 21 years ago with a deposit of $2,978.41. If the inte

jolli1 [7]

Use the attached formula.
exp = [log (total / principal) / n*years]
where "n" is compounding periods per year
exp = [log (7,194.66 / 2,978.41) / (365*21)
exp = log ( 2.4156042989 ) / 7,665
exp = log ( 2.4156042989 ) / 7,665
exp = 0.38302579382 / 7,665
exp = 0.00004997074935681670 

rate = (10^exp -1)* n
rate = (10^0.00004997074935681670 -1) * n
rate = (1.0001150685 -1) * 365
rate = (.0001150685) * 365
rate = 0.0420000025 
rate = 4.20000025 %
rate = 4.2 %

Yes, it's just that easy. LOL

If the length of the insect is 1.25 cm, then 1.2 is less than 1.25. This is because in counting 1.2 comes before 1.25

In a football tournament, the Bees scored 9 less than three times as many points as the Hornets. The Wasps scored 28 more points

Alinara [238K]

Answer:

The Bees scored 90 points.

Explanation:

First, let's prove that the equation is correct.

To create the equation, you translate the verbal statements into algebraic expressions.

Since, it is said that x respresents the number of points scored by the Hornets, that is your variable and all the verbal statements will be translated using x:

a) NUmber of points scored by the Hornets: x

b) The Bees scored 9 less than three times as many points as the Hornets ⇒v3x - 9

c) The Wasps scored 28 more points than the Hornets ⇒ x + 8

d) Together the three teams scored 184 points ⇒

x + (3x - 9) + (x + 28) = 184

Which indeed is the given equation: (3x – 9) + x + (x + 28) = 184

Now, complete the steps to show it, in the same order given:

1. Combine like terms.

Remove the parenthesis: x + 3x - 9 + x + 28 = 184

Combine the terms on x on the left: x + 3x + x = 5x

Combine the constants on the left: - 9 + 28 = 19

Write the result: 5x + 19 = 184

2. Use the subtraction property of equality.

Subtract 19 from both sides: 5x + 19 - 19 = 184 - 19

Due the operations: 5x = 165

3. Use the division property of equality. 4.

Divide both sides by 5: (5x / 5) = 165 / 5

Due the operations: x = 33

4. Use the variable to answer the question. How many points did the Bees score?

The expression for the points scored by the Bees is 3x - 9, so substitute x in that expression: 3 (33) - 9 = 99 - 9 = 90.

Answer: the Bees scored 90 points.
