Answer: ![\frac{13}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B35%7D)
Step-by-step explanation:
negative 3 over 7= ![-\frac{3}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B7%7D)
Plus 4 over 5= ![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
When adding fractions together, you should first change into a common denominator, then do the operation.
------------------------------------------------------------------------------------------------
= ![-\frac{15}{35}](https://tex.z-dn.net/?f=-%5Cfrac%7B15%7D%7B35%7D)
= ![\frac{28}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B35%7D)
+![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
=
+![\frac{28}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B35%7D)
=![\frac{13}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B35%7D)

Answer:
305
Step-by-step explanation:
This sequence es the sum of 3
5+3 =8
8+3 = 11
then
101 = 100 + 1
the fisrt date is 5
the another 100:
100*3 = 300
300 + 5 = 305
H/2+7 = 10
h/9 = 10
h= 10 x 9
h = 90
Answer:
VF= $3.281,42
Interes= 3.281,42 - 3.000= $281.42
Step-by-step explanation:
Dada la siguiente información:
Prestamo (P)= $3.000
Tasa (i)= 0,015/2= 0,0075
Cantidad de periodos (n)= 6*2= 12 semestres
<u>Para calcular el valor final del prestamos, tenemos que usar la siguiente formula:</u>
VF= P*(1 + i)^n
VF= 3.000*1,0075^12
VF= $3.281,42
Interes= 3.281,42 - 3.000= $281.42
Answer:
A) -18 B) r=10 C) x=-4
Step-by-step explanation:
A) 1d + 12 = 14-20
Step 1: Simplify both sides of the equation.
1d+12=14−20
d+12=14+−20
d+12=(14+−20)(Combine Like Terms)
d+12=−6
d+12=−6
Step 2: Subtract 12 from both sides.
d+12−12=−6−12
d=−18
Answer:
d=−18
B) 4(20+5) = 10r
Step 1: Simplify both sides of the equation.
100=10r
Step 2: Flip the equation.
10r=100
Step 3: Divide both sides by 10.
r=10
C) -2(5 + x) - 1 = 3(x + 3)
Step 1: Simplify both sides of the equation.
−2(5+x)−1=3(x+3)
(−2)(5)+(−2)(x)+−1=(3)(x)+(3)(3)(Distribute)
−10+−2x+−1=3x+9
(−2x)+(−10+−1)=3x+9(Combine Like Terms)
−2x+−11=3x+9
−2x−11=3x+9
Step 2: Subtract 3x from both sides.
−2x−11−3x=3x+9−3x
−5x−11=9
Step 3: Add 11 to both sides.
−5x−11+11=9+11
−5x=20
Step 4: Divide both sides by -5.
x=−4
