Answer:
9 1/2 or 9.5
Step-by-step explanation:
First you have to get the t all alone to find the value so you divide both sides by 2
19/2= 9 1/2 2t / 2 =t
t = 9 1/2
9 1/2 as a decimal is 9.5 so it could also be 9.5
Answer:
1=27 2= -1
Step-by-step explanation:
if three watermelons equal 60 divide that by 3 to get 20. 30 minus 20 will get you what the strawberries together make so divide by two to get 5. After subtract 5 from 3 to get -2 and since you did it in reverse think of it as a positive. So that equals 1. 20 + 1 + 7 is 27. For number two start at the bottom with the clovers since its only clovers.divide 12 by 3 to get 4. Then go up to the second equation 31-16 is 15. After divide by 3 and get 5. Then go to the next equation and do the same thing, add the sunflowers and then subtract the sum from both sides. 40 - 10 is 30. 30 divided by 3 is ten. After go to the last one. 5 - 10 + 4 is -1.
It is impossible to draw a parallelogram with 4 parallel lines (or to draw any quadrilateral with 4 parallel lines, for that matter).
The exponent of a number says how many times to use the number in a multiplication.
For Example, In 8² , the 2 is the number of times 8 has to be multiplied. In this case It has to multiplied by itself 2 times, 8x8 = 64 so 8² = 64.
Another example is 9³ since the number above is 3 we have to multiply 9 three times, 9x9x9 = 729 which means 9³ = 729.
Hope this helps
Answer:
3) 4x=15
6)b=$2.5
1) n= -12
Step-by-step explanation:
3. Given the equation ,
#Expand by removing the brackets:
#We then group the like terms to solve for x:
2+4x=17
4x=15
Hence, the equations equivalent is 4x=15
6. Let b be the cost of each bag of snack.
-Given that there are 4 friends who spent a total of $34 and each ticket costed $6.
-We equate the costs to the total to solve for b:
Hence, the cost of each bag of snack is $2.5
1) Given the equation
#First. we multiply each term by 3 to remove the fraction:
#We then group like terms together to solve for n:
#Divide all terms by -2 to get the value of n:
Hence n= -12
