What is 2y+3=3 (y+7)

Answers

Answer 1

Answer: y=−18 and tell me if you need the step- by-step :)

Answer 2

Answer: 2y+3=3(y+7)
-Use Distributive Property-
2y+3=3y+3(7)
2y+3=3y+21
-Minus 2y on both sides-
3=3y+21-2y
3=y+21
-Minus 21 on both sides-
y=3-21
y=-18

If Adam Ct. is perpendicular to Charles st. and Charles St. is parallel to Edward Rd. what must be true?A. Adam ct. is perpendicular to Edward Rd.
B. Adam ct. is parallel to Edward La.
C. Bertha Dr. is parallel to Charles st.
D. Dana la. is perpendicular to Charles st.

Answers

Answer:

A. Adam ct. is perpendicular to Edward Rd.

Step-by-step explanation:

We are given that,

Adam Ct. is perpendicular to Charles St.

Charles St. is parallel to Edward Rd.

So, we get the situation shown below.

It is required to find the relation between Adam Ct. and Edward Rd.

As, we can see that,

Charles St. being parallel to Edward Rd. and Adam Ct. being perpendicular to Charles St.

We get,

Adam Ct. is perpendicular to Edward Rd.

Hence, option A is correct.

Adam Ct and and Edward Rd must be parallel! (answer B). Take a look at the attachment: i drew the plan according to what we know).

(options C and D can also be true, but we don't know enough about the city to verify this)

Let event A = "math test" and event B = "Score: 90-100." Then find , where

Answers

To find the percentage of students who took the math test and received a grade of 90 or above, we need to calculate the conditional probability P(A ∩ B), which is the probability of event A ("math test") and event B ("Score: 90-100") happening simultaneously.

From the two-way frequency table:

The number of students who took the math test and received a grade of 90 or above is 20.

The total number of students who took the math test is 20 + 40 + 7 = 67.

Now, we can calculate the conditional probability:

P(A ∩ B) = (Number of students who took the math test and received a grade of 90 or above) / (Total number of students who took the math test) × 100%

P(A ∩ B) = 20 / 67 × 100% ≈ 29.85%

So, the percentage of students who took the math test and received a grade of 90 or above is approximately 29.85%.

4. Estimate the sum of 9.327 + 5.72 + 4.132 to one decimal place.18.729

Answers

Answer:

Hence, the estimate value of 9.327 + 5.72 + 4.132 to one decimal place is:

19.2

Step-by-step explanation:

We have to Estimate the sum of 9.327 + 5.72 + 4.132 to one decimal place

We find the sum of these numbers:

Sum= 9.327+5.72+4.132

= 19.179

Now we have to estimate the value to one decimal place

so, on approximating the value, we get the sum=19.2

Hence, the estimate value of 9.327 + 5.72 + 4.132 to one decimal place is:

19.2

The sum for those numbers is 19.179 NOT 18.729. HOWEVER the Estimation of the sum and the answer for this question is 19.2 because the decimal place you are finding has a number to its right that is greater to that decimal place so you add the one to the decimal place you are finding.

Find the slope of the line on the graph

Answers

Answer:

m =1/2

Step-by-step explanation:

Use two points on the line given.

(0 , 2) & (-4 , 0)

You are solving for the slope. The slope formula:

m (slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-4 , 0)

(x₂ , y₂) = (0 , 2)

Plug in the corresponding numbers to the corresponding variables:

m = (2 - 0)/(0 - (-4))

Simplify:

m = (2)/( 0 - (-4))

m = (2)/(0 + 4)

m = 2/4

Simplify the slope. Divide the common factor 2 from both the numerator and denominator:

m = (2/4)/(2/2) = 1/2

1/2 is your slope.

Answer:

0.5
