Answer:
12. -11
13. 2
Step-by-step explanation:
12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction
For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.
From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.
Your new equation is -10-8+7 = -11
13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))
- keep in mind there’s an addition between the two
Division and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17
Second multiply 5 x -3 = -15
Now you can combine the two answers using addition: 17 + (-15) = 2
Answer:
Step-by-step explanation:
arithmetic sequence formula: 
where 
is the first term and 
is the common difference
Given:
⇒ 
⇒ 
Given:
⇒ 
⇒ 
Rearrange the first equation to make the subject:
a = 32 - 9d
Now substitute into the second equation and solve for
(32 - 9d) + 11d = 106
⇒ 32 + 2d = 106
⇒ 2d = 106 - 32 = 74
⇒ d = 74 ÷ 2 = 37
Substitute found value of into the first equation and solve for :
a + (9 x 37) = 32
a + 333 = 32
a = 32 - 333 = -301
Therefore, the equation is:
A.) The clerk has - 16 oranges 20 apples 24 pears
he needs to put all three fruits into baskets without any leftover fruits
each basket should have equal amounts of each fruit
so to find the largest number of baskets he can make we have to find the highest common factor for 16,20 and 24
so lets find the factors for each of these
16 - 1,2,4,8,16
20 - 1,2,4,5,10,20
24 - 1,2,3,4,6,8,12,24
from the given factors the common factors for all three are 1,2 and 4
from these the highest factor is 4
therefore the largest number of baskets he can make are 4
in each basket there will be
4 oranges 5 apples 8 pears
answer is 4 baskets
Answer:
206
Step-by-step explanation:
The formula for this problem would be -310 + 13(8) which = 206
