8x + 4 = 3 (X - 1) + 7

Igoryamba

Answer:

Step-by-step explanation:

8x + 4 = 3x - 3 +7

u first expand the bracket as I have done above

then u evaluate those who have like terms close like -3 + 7

8x + 4 = 3x + 4

then u group like terms ie. the values with the variable x on one side of the equation and the ones without x on the other side of the equation

8x - 3x = 4 - 4

8x - 3x = 0

5x = 0

then u divide both side by the coefficient of x

0/5 but any number divided by 0 is 0, so x = 0

In a test (+4) marks are given for every correct answers and (-3) marks are given for every incorrect answers 1) Tahiya answered

stealth61 [152]

Answer:

Tahiya attempted 3 incorrect answers.

Helmin attempted 11 incorrect answers.

Step-by-step explanation:

Correct = +4

Incorrect = -3

1) Tahiya got 12 correct answers and scored a 40, the number of incorrect answers was:

$4*12-3I=40\\I=\frac{8}{3}\\I=2.67$

2) Helmin got 5 correct answers and scored a -14, the number of incorrect answers was:

$4*5-3I=-14\\I=\frac{34}{3}\\I=11.33$

In both cases the number of incorrect answers obtained is a fraction, which means that either the data provided is inaccurate, or that the scores obtained by the students are approximate. Let's round the number of incorrect answers to the nearest whole answer.

Tahiya attempted 3 incorrect answers.

Helmin attempted 11 incorrect answers.

Please help!<br> Having lots of trouble with math :)

So x and y are supplementary because the angle beside X is 90º so all together it’s 180º

And each side should add up to 90º

So x and y should each be 45º if I’m not mistaken, and then z is (I forgot the proper vocab term for this) right flippity across y so it should also be 45º
