Answer:

The expression is: [tex]-30n + 70 = -80[/tex]

Step-by-step explanation:

Given

[tex]n = 5[/tex]

Multiply both sides by 3

[tex]3 * n = 5 * 3[/tex]

[tex]3n = 15[/tex]

Subtract both sides by 7

[tex]3n - 7 = 15 - 7[/tex]

[tex]3n - 7 = 8[/tex]

Multiply both sides by -10

[tex]-10(3n - 7) = -10*8[/tex]

[tex]-30n + 70 = -80[/tex]

To verify: Substitute 5 for n

[tex]-30 * 5 + 70 = -80[/tex]

[tex]-150 + 70 = -80[/tex]

[tex]-80 =-80[/tex] ---- Verified

Answer:

(-1, 5)

Step-by-step explanation:

this is correct

The new coordinates of the vector (5,1) after rotating it 90° clockwise about the origin would be (-1,5).

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Rotating a vector 90° clockwise in a 2D coordinate system can be accomplished by "flipping" the vector's x and y coordinates and then negating one of them.

In this case, the original x-coordinate is 5 and the y-coordinate is 1.

When we negate the x-coordinate and swap the positions of x and y, we get the new coordinates of (-1,5).

Answer:

2) 7/-8

Step-by-step explanation:

7/-8 because there is one negative meaning that the whole fraction will be negative. If there were two negatives, or none, it would be positive. The original fraction, -7/8, is a negative. Also, the actual numbers are equivalent as  well, 7/8 and 7/8.

The date and time 12,345 minutes after the start of the new year will be 9 January.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

A new year begins at 12:00 AM on January 1.

The number of days in time 12,345 minutes will be

⇒ 12345 / (60 x 24)

⇒ 8.5729 days

Then the date and time 12,345 minutes after the start of the new year will be 9 January.

Answer:

-1.4

Step-by-step explanation:

There are five increments between -2 and -1, so we find the difference between -2 and -1, which is 1. Divide 1 by five (increments)=.2

This means that every increment is worth 0.2.

If we see it from the left to right, from -2, there are 3 increments to the right, so multiply three by 0.2 which is 0.6, add 0.6 to -2, which is -1.4.

Answer:

292

Step-by-step explanation:

take 365x 4/5=292.........

The number of students having a cell phone if Approximately 4 out of 5 students in Mrs. Haynes 7th grade math class have cell phones, and there are 365 students in the 7th, is 292.

The fundamental concept of making the same number of additions repeatedly is represented by the action of multiplication.

The results of multiplying two or more integers are known as the products, and the factors that are used in the multiplication are referred to as the factors.

Given:

Approximately 4 out of 5 students in Mrs. Haynes 7th grade math class have cell phones, and there are 365 students in the 7th,

Calculate the number of students having a cell phone as shown below,

The number of students having a cell phone = 4 / 5 of 365

The number of students having a cell phone = 4 / 5 × 365

The number of students having a cell phone = 4 × 73

The number of students having a cell phone = 292

Thus, The number of students having a cell phone is 292.
