Ok so assuming that the 'x' means multiply and not 'x' as in placeolder we do
PEMDAS
parenthaseees
exponents
multipilcation or division
additon or subtraction
parethasees simplify first
(8+7)=15
(9-3)=6
now we have
2x(15)-6/2x(6)
multiply
2x15=30
6/2x6=36/2=18
now we have
30-18
12
answer is 12
Answer:
x = -6
Step-by-step explanation:
y = -x equation 1
x + 6y = 30 equation 2
using equation 1 in equation 2 we have:
x + 6(-x) = 30
x - 6x =30
-5x = 30
x= -30/5
x= -6
Answer:
258.75km
Step-by-step explanation:
345/4=86.25
Can travel 86.25km an hour
86.25*3=258.75
Therefore it can travel 258.75 in 3 hours
Answer:
3(50 g) = 150 g
Step-by-step explanation:
If you mean 25% sugar by mass, then 1/4 of the total mass is sugar, and 3/4 is water. So you need 3 times as much water as sugar.
3(50 g) = 150 g
Answer:
3,333,333 spacecraft
Step-by-step explanation:
To get the number of spacecraft that would fit between earth and moon <em>divide the distance by the length of the spacecraft</em>.
When
is divided by 360 the quotient will be 3,333,333 and the remainder will be 120.
It means 3,333,333 Apollo 11 spacecraft will fit between earth and moon but still 120 feet will remain and no more spacecraft can completely fit in it.
