Answer:
4
Step-by-step explanation:
Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.
Answer:
20:100
Step-by-step explanation:
We know that percentages are out of 100. The rose garden is 20 percent of the garden. Which is 20 percent/100 percent. A ratio says how much of one thing there is compared to another thing. Therefore we are comparing 20:100. You can also simplify this ratio to 1:5
C because there are 60 seconds in a minute so if you multiply 600 x 60 you get 36000
Answer:
y=3x+19.
Step-by-step explanation:
1) according to the condition the line 't' is parallel to the line 's', it means, the equation of the line 't' is: y=3x+C, where C - unknown number.
2) in order to calculate the 'C', it need to substitute the given coordinates into the equation of the line 't', then:
-2=3*(-7)+C, ⇒ C=19.
3) if C=19 and the equation of the line 't' was y=3x+C, then it is possible to make up the full required equation:
y=3x+19.
