Answer:
5 1/3 x+8 1/2 =3 1/3 ?
the correct answer is -1.774
Step-by-step explanation:
51/3x + 81/2=31/3 In order to find x, we follow BODMAS rule
so we have,[ 51/3] x + 81/2 =31/3
we have 51x/3 + 81/2=31/3
we collect the like terms;
51x/3= 31/3- 81/2
finding the lcm
51x/3= 2[31} - 3{81}/6
51x/3= 62-243/6
51x/3= -181\6
by using cross multiplication
we have;
6{51x}= 3{-181}
306x = -543
divide both sides by 306
we have;
x = - 1.774
check your answer from
306x=-543
306{-1.774}= -543
-543= -543
12$ Cuz 6X2+=12........................................
Answer:
4/5 or 0.8
Step-by-step explanation:
1/3x = 5/12
<em>cross</em><em> </em><em>multiply</em>
(12×1) = (5×3x)
<em>divide</em><em> </em><em>through</em> <em>by</em> <em>1</em><em>5</em>
x = 12/15
x = 4/5 <em>o</em><em>r</em><em> </em>0.8
Step-by-step explanation:
180 - 34 = 146
one angle is a right angle, angle across it is 146, 360 - 90 - 146 = 124
divide that by two to get the measures of the remaining two angles (62 degrees)
180 - 62 = x
118 = x
Answer:
Number of Pennies = 30
Number of Dimes = 90
Step-by-step explanation:
Let the number of pennies be p and number of dimes be d
We can write 2 equations and use substitution method to solve.
<u>Total value of all the coins is 9.30:</u>
We can write:
0.01p + 0.1d = 9.30
Note: value of penny is 0.01 and dime is 0.1, in dollars
<u>Number of dimes is 3 times number of pennies:</u>
We can write:
d = 3p
Now putting 2nd equation in first and solving for p:
0.01p + 0.1(3p) = 9.30
0.01p + 0.3p = 9.30
0.31 p = 9.30
p = 9.30 /0.31
p = 30
Now we know d = 3p, so d = 3 (30) = 90
Hence
Number of Pennies = 30
Number of Dimes = 90
