determine wheter 3x+12+x is equivalent to 4(3+x). use properties of operations to justify your answer. please help! answer only if you know!
Answers
4(3 + x) = 12 + 4x because 4 times 3 is 12 and 4 times x is 4x so you add them to get 12 + 4x which can be rearranged to equal 4x + 12
So in short: 3x + 12 +x is equivalent to 4(3+x)

amounts of fruit you could buy. If you buy 10 pounds of bananas, how many pounds of
apples would it be possible to buy?
Answers
0.34x+0.49(10)=6
0.34x+4.9=6
0.34x=1.1
X=3.23
Answer: it is possible to buy 3 pounds of apples
Final answer:
A linear equation is written to represent the cost of buying different amounts of fruit. If one buys 10 pounds of bananas, they could also afford to buy approximately 3.24 pounds of apples.
Explanation:
The esential first step here is to write a linear equation that can represent the different amounts of fruits you could buy. Let's denote the pounds of bananas and apples as b and a respectively. The cost per pound of bananas and apples can be represented as 0.49b and 0.34a respectively. The total cost is $6.00. Hence the equation becomes:
0.49b + 0.34a = 6.00
With this equation, we can calculate the possible pounds of apples you could buy with 10 pounds of bananas. Substitute b = 10 into the equation:
0.49(10) + 0.34a = 6.00
4.9 + 0.34a = 6.00
By subtracting 4.9 from both sides of the equation and then dividing by 0.34, we can solve for a:
a ≈ 3.24
Therefore, with 10 pounds of bananas, it would be possible to buy approximately 3.24 pounds of apples with the remaining amount of money.

so he paid 29.50 dollars more
29.50/0.25=118
so he texted 118 times
now subtract 30 from each side leaving you with:
.25x = 29.50
now divide by .25 on each side.
x = 118

Hi there,
No. 1:
The answer is 8.2 ft, for sure.
Having this technique in mind, can you resolve the rest of 4 math questions, by yourself ? It is quite simple, isn't it ?
Green eyes.
find the perfect squares above and below the target number
guess
example
sqrt of 99
9^2=81
10^2=100
99 is between 81 and 100, closer to 100 so therefor pick 10.9 or something
1.
if we estimate
8^2=64
that is close to 68
8.2^2 is probably closer sinnce is is bigger than 0.2
therefor the answer is A
2. estimate
12^2=144
13^2=169
148 is betwen 12 and 13
pick B
3. 114
square aera=side^2
10^2=100
11^2=121
see if it is more than 10.5 or less
which is closer 114
100 or 121
121 is closer
therefor we guess that it is greater and therefor we should guess 11 yards
4. area=side^2
196=side^2
luckily we remembered tat 14^2=196
1 side=14 ft
perimiter=4side
P=4*14=56 ft
5.
area=side^2
480=side^2
sqrt both sides
√480=√16√30=4√30
aprox sqrt 30
between 5 and 6, lookks like in middle
aprox 5.5
4*5.5
perimiter is times 4
4*4*5.5=16*5.5=80+8=88 feet
answer is D
A. 136
B. 126
C. 45
