Step-by-step explanation:
<em>(-2)-(+15)=(-17)</em>
<em>the</em><em> </em><em>diffe</em><em>rence</em><em> </em><em>between</em><em> </em><em>those</em><em> </em><em>two</em><em> </em><em>temp</em><em>erature</em><em> </em><em>s</em><em> </em><em>is</em><em> </em><em>(</em><em>-</em><em>1</em><em>7</em><em>)</em>
Step-by-step explanation:
collin is correct and incorrect at the same time. when you solve this, you start with adding like terms.
10x and -11x will be added together to be -1x, after we figure this out, we solve.
-1x+7<-20
-7 -7
-1x<-27
/-1 /-1
x<27
after you solve, you notice that x is less than 27. collin has the correct answer for solving the equation, but if were looking on a more technical note, he would be incorrect because he said the answer is 27, when the answer is actually less than 27. therefore, collin has solved the inequality correctly, but he has said the answer incorrectly
Answer:
the answer is 240
Step-by-step explanation:
If 4% are defective, then out of a batch of 250, the number of defective is
4% x 250 = 4/100 x 250 = 10 defective
So, the number of not defective is 250 - 10 = 240 good!
Answer:
No x-intercept/Zero
Step-by-step explanation:
Substitute f (x)=0
Solve the equation
There is no x-intercept/zero
Answer:
30%
Step-by-step explanation:
Presuming that "survey 3,000" is the total and "900" is the factor who had problems then dividing the total amount by the amount of problems like equal the relative frequency of people that had problems
Math:
Amount of people you had problems / Amount of people who bought the new car.
900 / 3000 = 0.3
Now you need to multiply by 100% (because % in this case is a unit/measurement)
0.3 * 100% = 30%
