Carlos just took 40 question math test he scored 75%

So he missed 10 questions and got 30 right

Step-by-step explanation:

To find the answer we need to find how many times 40 can go into 100. it can go into 100 exactly 2.5 times. So 2.5 times 40 will equal 100(100%) This also means that 2.5 times X should also equal 100.

To find X we can do 75 divided by 2.5. When we do this, we get 30. So he got 30 questions right and missed ten.

Another way to find the answer is to just do 0.75 or 75% times 40(total amount of questions)

the image of (6, 9) under a dilation is (4, 6). the scale factor is

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
